Oh I dont think they can possibly exist as we now know them. The 'Corp' is a legalese protection racket. No state, no corp as a person. No corp aa a person, the actual people are responsible for any malfeasance and crimes.

That's exactly what i argue with ancaps, LLC business are more product from statism than anything related to free market
Anacap's an odd thing. I found it appealing at first, but the more I read about it or listened to people speaking on it, the less I liked the as a whole. Seems a pure ancap community / society would just be cut throat profit driven assholes to be honest.
