Given the context of the OP, I'm guessing you are making a motion to completely remove anima simply because it can run out, and then adversely affect the decision to even play.

Given that interpretation, I'd like to say that the solution targets the wrong problem. The problem posed is that travel is inefficient. The solution (which is coming) is mounts and airships. When those arrive, I bet anima problems will be reduced since most people will mainly use it in immediate need situations. It will likely become a resource more valuable to the time-starved solo casual player.

Anima abuse, on the other hand, is a problem that could possibly be solved by the abolition of anima, though I would likely argue against such extreme methods.
