I’m pretty sure everyone is allergic to having their skin and lungs rubbed with mica.

Moon dust is functionally a lot like asbestos. It is composed of a sizeable amount of tiny shards of rock that aren’t great for your lungs.

So, if someone were to crash the moon into the earth to stop it escaping, as many as 1/12 of the population could experience a reduced quality of life?

Might need to consider not doing that I suppose.

The sample size is at least a little bit bigger…

Some guy stole moon rocks (presumably still had moon dust on them) to bang his gf on them.

what’d be the smallest sample size that would yield a relevant result?

30? 1000?
