The logic embedded in Supertasks and the Banach-Tarski Paradox has always seemed strange. It's not flawed, but it's so counterintuitive that it can seem like evidence that something in the logic of infinities must be wrong.

Banach-Tarski isn't so much evidence that infinity or Choice is wrong, as evidence that the reals aren't a particularly good model of the real world.
