“Government” is a very vague term.
Anarchists are opposed to rulers, not rules. We want to be able to establish our own rules directly. The form of social organization depends largely on the anarchist you’re talking to, but most of us support some variation on federated communes utilizing direct democracy and delegates, not representatives.
Honestly, just read The Conquest of Bread by Petr Kropotkin. It’s available free at thebreadbook.org
