Pal, you're still merging with it.

Also I'm certain that somewhere, at some point in history, someone said "You can't make x character fly" until someone went there and did it.

Trying to keep quality in fiction is one thing I agree with.

Trying to say "X can't happen even if properly executed" is just trying to take someone else's verse and say "This can't happen", at which point we would be just restricting other people.

If we have an actual instance of such a thing even in a professional work, ruling the possibility out is an obvious no. Granted, you'd need to write quite well to actually pull that off without making it suck.
