It’s not like the United Nations would stop existing. It’s also not as if interstate trade would stop (I mean, unless a state tried to literally enslave its population, that’d stop interstate trade really quick). If South Africa couldn’t manage Apartheid due to pressure from other nations, there is zero chance Louisiana could magically reinstate slavery. This is an absolute straw man.
