Yes to all of those. In fact many of those are massive markets.
Hofs bunny ranch is a famous brothel in NV
Booz Allen makes and maintains the nuclear fleet including the Sentinel ICBM
Textiles factories are globally known to be industrial slave camps for a non trivial portion of the supply. Even worse for Mica mines.
Etc…you can fill out the rest
I think most textile factories in Western countries are not slave camps, precisely because we regulate labor.
Sure, that's why 99% of clothes are made offshore, but if we had something like tariffs on those (or requirements to prove that the actual factory adheres to labor and environmental standards), maybe more would be made "at home"? Similarly: Chinese cars undercutting US/German ones.
Booz Allen actually makes what now? The Sentinel is still in development by Northrop Grumman and there is some program management done by Booz, no?
The existence of something doesn’t prove the universality of that same thing. All of the things you cite are regulatory exceptions to broad prohibitions which proves my point: society can and does restrict commercial activity.
Go open a brothel in NYC. It isn’t legal.
Go buy a nuclear bomb. Your ownership is illegal.
Go open textile mill in the abandoned buildings in North Carolina where children used to work and hire children to work the line. That will be illegal.
