You’re moving your goalposts at this point. The original point was literally about people claiming land in a primitive extraction system.
In the modern era people also don’t just walk up and demand bushels of barely from farmers, so ignoring the entirety of a comment to reply with how changing the context makes it irrelevant is just a bad faith discussion tactic.
Yes, a modern economic system is hard to develop inside of a single comment. I hope we can at least agree that feudalism is bad, despite it respecting the Lord’s property rights, and also that no one is okay with letting the Saxon horde take all our grain.
And, to jump straight to your questions about the modern day: I would propose a system where the vast majority of the engines of production would be worker owned, allowing them to select their own management as primary shareholders.
By merit of existing in society people would be entitled to food, shelter, medicine, a means to better themselves, and the basic dignites of modern life (clothing, the ability to have children, the ability to do more than sit in the floor and stare at the wall).
Beyond what’s needed to provide these basics, the excess value produced would be given to those that produced it in the form of “currency”, which can be exchanged for “goods” and “services”.
