I’ve never thought of Agorism as a leftist ideology 🤔 can you give your definition of Agorism?

Regulatory capture is not an inherent part of capitalism. It is a feature of state capitalism and incompatible with Anarcho-capitalism.

As to hierarchies, I suppose that depends on what you mean. Aggression-based hierarchies are incompatible with Ancap.

Having a hierarchical structure like “boss and employee” within a business, on the other hand, is likely, as contracts like “if you do x work for this company you will be paid y amount by z date” is completely voluntary and acceptable.
