How about advancing the frontiers of science? That alone is worth it, it is not?
You seem to want to halt all further research into alternative energy and settle with the current state of our solar/wind capabilities, which is strange.
Fusion is a poor kind of science. It's very inward focused, answering questions that are relevant to fusion but not much else. As pure science, it would not merit the $$$ being focused on it.

We can do both.
