Yes, anything on the battlefield counts as a permanent.

I mean if you have a doubling amount of them, you need enough that you can lose 7 per turn and still recover. So you need at least 7 to begin with, and you could block forever.

The real flaw with the comic is that Emrakul has flying, so squirrels can't block it anyway, unless you give them all flying.

Really though, it's meant to be a game-winning card. It does so much that it's very hard to survive and recover if it's on the board.
