Well, I don’t have an opinion on this, but since I live in Denmark, I can share some details from the debate around this tunnel:
Some would rather upgrade the existing route from Copenhagen to Hamburg from the current 180/200km/h to 250km/h, to also benefit domestic train travel, and eventually make domestic short haul flights and polluting fast ferries obselete.
Also, the the line from Copenhagen to Hamburg will also be just 200km/h, which many think is unambitious, not future proofing for future high speed 250km/h trains, and some even think the tunnel should’ve been built without car lanes at all, but 4 rail tracks instead, forcing drivers and trucks to take the old long way around.
And then, for the cost of the project, the money could’ve instead been used for a greater Copenhagen area light rail network, or dozens of BRT lines and an S train expresstunnel, or a nationwide high quality bicycle path network, port rail links, battery trains, and line speed upgrades and double tracking.
If anybody has any questions, about the project, Denmark’s public transit, or Denmark’s transportation in general, I’d love to answer them as best I can :)
I would argue that in terms of logistics, it is definitely going to make a huge difference. And when it is built, and it will stay okay for a long time. It is a proof that we can construct quite simple things like this, and no need to dig under a large stretch of water. This is a tunnel that allows faster transportation of goods between Sweden and Germany, bypassing Denmark, well, mostly bypasses Denmark. In future, goods from Norway will be more easier to transport by land too.
In 2019, the Bundesrechnungshof commented that "in view of the current traffic forecasts, it is questionable whether the benefits of the project will increase to such an extent that the expected costs are justified under economic aspects".
lets see how much the project will cost in the end, but my bet is it will not be worth it in the end
Indeed, it is an investment to lay foundations for the future ease of access and transportation. It is a civil investment, which later, CAN BE USED BY armed forces. As that tunnel shortens the travel between Sweden and Germany, considering what the state of the world is today. You bet it will make a huge difference in logistics, be it either civilian or military.

from an engineering point its an impressive feat, but probably a waste of money unfortunately
