Can you guess how the world would be with anarchy ?

It depends. The true definition, with is roughly law without force, then it wouldn't be too bad. Sounds like it would just be a non corrupt world. However, modern day groups like ANTIFA, it would suck. Things have been blown out of proportion honestly to the point where anarchy, or "anti-fascism", almost looks like fascism.

I think you confuse anarchy with a version of the so called Hobbesian nightmare. Anarchy simply means "no ruler". It does not mean "no rules".

Many anarchists, like Anselme Bellegarrigue, have complained that "vulgar error has taken 'anarchy' to be synonymous with civil war
Under anarchy, creation (natural law purists would say discovery) and enforcement of the rules or social norms are decentralised rather than monopolised by a single institution currently called "government" or "the state". Anarchy means that no institution is exempt from the rules.

Ithink it’s c , good luck on whatever : )
