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.
OP, if there was a viable way of making communism work, some one would have done it already. And inb4 if external pressure and/or internal grinding makes your system collapse, then it does not work
I mean, that is kinda my stance.
On the other hand, I am always open to being proven wrong.
