You are not permanently tied to your landlord, nor is your landlord your judge and president. You don't usually work for your landlord, either.
Capitalism is different. It still sucks and exists because of the squeezing out of surplus value. It isn't feudalism.
As for economies being lowly tools, they're not. They're quite literally the most important part of society. They're how we eat, drink, and survive. Unfortunately we live in a class society, and have done so ever since a couple of dudes during the dawn of agriculture started racketeering. As a result, "a few thousand sociopath families" have distributed resources in their own favour for a very long time, and will continue to do so until class society and the state are abolished.
Socialism is working out fairly well for the Zapatistas rn. It worked out well for Catalonia until the PCE and the Republicans backstabbed the POUM and CNT, leading to the fascists winning against a weak and broken-up left.
The platformist organization itself has a high degree of theoretical unity. The platform was invented because the Ukrainian anarchists were so disparate and constantly bickering about theory that they couldn't form a consistent strategy.
Dual organizationism and social insertion are not necessarily platformist. They precede it by many decades.
Anarchism is omitted from the name because it is implied. There are no non-anarchist platformists.
If he is a Big Bang character, he would very much not be an Antifa supersoldier, I can guarantee that.
