How a particle physics desert could arise in a natural manner
If we presume that particles are spun from higher-energy physics then this presumption ought to change the fundamental nature of how we view particles.
"Particles" should be considered as (changeable) elements within this higher-energy physics environment. But, they are elements which have become immune to this environment. They have become bound objects, which thought they might alter in response to high energy flows remain the same kind of thing.
These bound objects have formed contractual flows of energy between themselves to preserve themselves. And, by doing so they have frozen in the nature we observe in lower energy physics. They have become our present particles with their present properties.
However, we can also reasonably ask: shouldnt our forces be changing as well, in response to the changing nature of our bound objects? How do stable forces come about?
Stable bound objects and stable forces will arise at the same time, and for the same reason: when our bound objects are stable with respect to an environment created by our forces. Otherwise one of the environment or our entities will do work upon the other.
amalgams vs simples
There is a view of our present particles as simples. We discover pre-existing particles at higher energy scales.
But it seems more natural to say that particles are entities which act in relation to each other with certain forces.
These forces can combine particles into larger amalgams with a new net-effect force that operates between these new amalgated particles.
At certain temperatures and conditions these amalgams become immune to energy flows from the higher-energy physics.
In part this is due to the nature of the amalgams which have developed. But, in part I think it is also due to the nature of the new forces which have developed.
a twofold conception of forces
This leads to a twofold conception of present forces:
They preserve past contracts
They relate our present bound objects (our particles) to one another.
This explains the nature of discrete, preserved quantum numbers in interactions.
As well, the first point leads to a natural conception of a high-energy desert, at energies lower than the freezing in of particle properties.
Over a large temperature and physics range higher-energy physics forces wont be directly present, though they will remain responsible for our measurements of the attributes of our particles.

Here is a hypothesis: if particles have internal structure then a particle physics desert could arise in a natural manner

Yes, from the perspective of the higher-energy physics theory, the lower-energy physics theory has emerged. Higher energy physics particles have formed amalgations that are resistant to changes from their environment.
And the forces present in this environment has changed as the high energy particles amalgate. These amalgams will over time become bound objects resistant to environmental forces, responding to them but not being changed by them. Eventually they will settle to form the particles within our present physics.
If I'm contractuallly bound to you then we are engaging in transfers of energy between ourselves to maintain ourselves in some state. A simple example would be the earth and sun exchanging energy gravitationally to maintain their rotation around their common centre of gravity.
Here, we get a little more. If a set of higher-energy physics particles become contractually bound together to form a particle in our effective field theory then they must necessarily act in manner that is
a.) codetermined - like the atoms within a molecule, they move as one. The motion of the molecule and the motion of the atoms are conjoined. To say one moves is to say the other does.
b.) constant - they must travel in a way that does not engage in net energy exchanges with the external environment. There motions are fully determined by their internal relations. Their contractual relations.
If a higher-energy physics particle does exchange energy with another entity then there is a causal change to the particle within the effective field theory.
Though we are talking about interactions these mild causal conditions are enough to get us back to a standard view of fields. We get back our (excellent) standard model.
But, the changed perspective does bring a little to the table. The heart of saying contractual relations is placing particles as ontological entities before spacetime ( a common, causal worldline to which measurements are, possibly probablistically, localised.)
When our length scale changes attributes like mass which depend on the length scale alter in response. Lets flip this perspective. The attributes of particles alter and this induces us to say that the length scale has changed.
Why?
1. Unraveling lengths won't necessarily unravel new physics.
We place causality within our physical interactions and not a length scale at which which we take our measurements. When we say length scale we have in mind something continuous in character. A length is a portion of a continuous thing, a stavle background environment that underlies all of physics. But does this microscope analogy work to all levels? I'm not certain that the environment we are currently determining our lengths from relates to the environment where higher physics emerges. So some arguments based on this belief might not make sense.
As we increase in temperature we need not smoothly transfer from one regime to another. Certain kinds of proablistic arguments might fail, we might not have a sensible notion of high-energy physics processes occurring with a certain very low probability at a certain temperature. Ramping up the temperature and examining the data for rare signals might fail as a strategy. Or, better: I dont see why it must necessarily succeed.
You might not get traces of new physics till you reach the point where present physics no longer protects past physics objects. So you get a desert and preservation of discrete quantum numbers over a vast temperature range.
2. We can treat particles, and the relationships between them, as more primary than spacetime
I believe the attributes of particles are physical in nature.
The elimination of the classical vaccuum combined with the notion of a field leads naturally to a notion of HB loops. These are loops which return to our entity without interacting with the external environment in a manner that leads to a net transfer of energy. There is no classical vaccuum to impede or alter their motions.
For me, these loops and their properties when localised to our worldline, correspond to all the possible properties of a particle. Attributes are physical in nature. And, a particle is the bound object which is the sum of these attributes.
String theory is then perhaps an attribute theory. Its a theory of the containers, the collection of hb loops, which have become our particles.
I explained the switch in perspective and why it might be useful more fully here: https://figshare.com/s/4b1f1473b1f1fbd1d761
