There are two definitions of Anarchy in the society. Leftists think it’s some magical utopian self governing system with no upper authority, while everyone else understands it as just state of no laws being enforced.

I leave impossible utopia to others, and answer with common definitions:

Libertarian framework postulate reduction of state to absolute minimum, leaving everything to free market forces. (for better or for worse)

Anarchy is temporary state at which for some reason (war, cataclysm, ect) there’s no framework at all. It’s temporary because some people organize, and some sort of structure emerges
