This is the central issue. Because grants are incredibly competitive, there is no reason to give money to someone who is going to do something that has already been done. You can make arguments for doing the same experiment with a different methodology because of advancements in technology or something, but you can't propose to do a true replication experiment.

You could then be inspired by a paper, replicate the previous study as a process for your new study, thus hiding replication inside a novel-aimed grant.
