| Aug 7, 2022 at 8:15 | comment | added | Keen-ameteur | I revised the question and added the condition of being compact, since I was hoping for something more general, but I do not yet how to exclude the dense sets. | |

Revised the question following suggestions.

| Aug 5, 2022 at 17:13 | comment | added | mlk | You will definitely need some sufficient notion of niceness, with the obvious standard counterexample being the open, dense sets of arbitrary small measure you can construct as the union of a sequence of smaller and smaller balls around any countable dense set. (Btw, this set should really have a name, since it comes up so often in similar questions...) | |
