comment Can an uncountable family of positive-measure sets be such that each point belongs to only finitely many of them?
Oh, I was being obtuse - you only needed that there are at least countably many sets in Γ of measure greater than ε. Sorry. And thanks for answering my question! I'll leave this up for a few days so others can learn from it, then award the bounty.

This looks great, but I'm still stuck at one point: how do you show that the collection of $E_i \in \Gamma$ with measure $>\epsilon$ is countable? You show that it can't be finite, but why couldn't it be uncountable? (Sorry if I'm being obtuse.)
