> Still, even without capitalism, you'll have to contend with the issue of how to cover operational expenses

You're still thinking in the framework of capitalism.

Let me be clear that I think that doing anything but capitalism is bound to fail while we're living in a resource restricted reality.

Nonetheless, if we want to think about it for arguments sake: there are no costs associated without capitalism, only necessary work and resources. It's really hard to think without the restrictions of capitalism for me, because that's the only way I've ever experienced and it's so effective at prioritizing resources and productivity. Anything else has historically always fallen short.

Though it's still a pretty fucked up and heartless system
