One counter argument is to note that math has been "unreasonably effective"

This
seems much more consistent with mathematics being descriptive rather than
prescriptive.
Or equally consistent, at least. Assuming that maths is broader than what is required to
describe (or generate) our universe, this is equally consistent with the MUH.
I don't think it's equal. If MUH is true then all those other mathematical theories must
be realized in some other universes where they are not just approximations. Then it's no
longer the case that mathematics is unreasonably effective in picking out our universe; it
could "pick out" any one of them. Either it would just be chance that we're in THIS
mathematical universe, or there's an anthropic selection that prevents intelligent beings
in universes with different mathematical bases.
