- Don't see why. The issue is whether there is any reason to worry about
- measurability in integration theory. If you don't mind the possibility
- of non-measurable sets, I don't see why Banach-Tarski should bother you.
-
- If you think that every "real world" set should be measurable, and hence
- Lebesgue theory is a waste of time, then you object to more of classical
- mathematics than just the axiom of choice.
-
- Not so?
