I don't think you fully follow. The skills can't be regulated: they're pure research. The US research community will continuing doing the fundamental enabling work relied on by exploit developers; it's just the people who do the testing and integration work who'll have to have their paychecks sent to Southeast Asia.

It's a very difficult problem.

There's also some bigtime cognitive availability bias happening here. We read lurid stories centering on "zero-day exploits" and say "something must be done". But no matter what these articles say, it seems cosmically unlikely that an exploit dealer is worth a billion dollars; the entire exploit trade is a rounding error compared to the switching and filtering equipment companies knowingly sell China and Iran for use in putting dissidents to death.
