Would the manufacturers make equipment that only put out 50 watts?

I think they would if the market existed. In JA there is a class of 10W HF
hams, and there are all sorts of nice 10W HF rigs available there.

But let's just suppose that the manufacturers continue to build only 100W HF
rigs for the US market. It's not the manufacturers responsibility to comply
with the power limits. That responsibility lies with each individual
licensee.

In my experience, hams are almost universally scrupulous in observing the
limitations that their license grant imposes on them.
