Yeah anarchism is a lot of theory and at this point, someone calling themselves an anarchist in good faith would be referring to it as a kind of ideology or faith rather than some end goal in their lifetime. At best anarchist thought right now can guide you like a religion to make you more pragmatic and participate in pro-social programs in your community.

It's funny because unfortunately, as far as I understand it, this meme uses anarchism in the incorrect meme-y way that people understand it. I.e. as an angsty "no rules, mom!" way. Anarchism as written by people who actually sat down and thought about the practicality of it would probably see someone or a group of people who sit down all day and make it their "job" to come up with agreed upon rules. Not as a leadership or a hierarchy, but just because division of labor is necessary for a flourishing society and because "no murder or we kick you out" is not a rule you should be letting people who live with you make for themselves.
