I see this way too often here on Lemmy, so I want to post this. Starting a commune is legal in most countries. If you believe in communism, you can found a commune and show us all how great it is.
You lack money? Well, that is literally what stock markets and venture capitalists are created to solve. If you are ready for an IPO, you can sell shares to raise funds. If you are not, you can get Venture Capital in exchange for shares until you are ready for an IPO.
Getting rid of capitalism means you need to find a different way to obtain funding. And if your system relies on government charity (some government board handing you money) or on taking it violently, than your system sucks.
The thing is, it can only ever work if it is chosen voluntarily by every participant, and it requires that everyone be committed to relentlessly work on themselves to root out their own selfishness.
Marx was right in the sense that humans are by nature selfish, but but he was wrong in thinking that selfishness could be abolished by force. What past experiments have shown is that if communism is violently imposed (i.e. via revolution), people will just find other ways to be selfish. For instance, if hoarding wealth is impossible, but everyone’s income is guaranteed no matter what, people will simply try to find ways to work as little as possible.
There IS an example for where communism DOES work BTW, and that’s functional, healthy families. Think about it: since children are naturally weaker than adults, parents do have to work harder in order to provide them with food and education, but as the parents grow older and weaker, the children become stronger and more capable, so they can provide for their parents in their old age. It really is from each according to their ability to each according to their needs.
