Yeah, it’s a goal, not a method. Even with a democracy/republic, there are so many different versions of it that exist. Is there a parliament? Is there a central leader? Who can vote? What happens if people can’t agree on who should be in charge?

Anarchism is a large set of ideals. There are a lot of people who have thought about how to make it work. Any issue people have with it, I promise you it’s been considered. Everyone probably won’t agree on what the solution should be (because that’s always the case), but it has been thought about.
