It's utterly irrational, promoted by those who sue or sell "mitigation" or
pols looking for cheap votes.

Remember "Prof. Harold Hill" in "The Musicman"? Manufacture a crisis, sell

I'd bet that at least half of the houses built before 1960 have detectable
levels of mercury in the bathroom or bedroom from dropped thermometers.

YMMV,
