You could have agriculture without modern capitalism.

We have people who treat Eve online optimization like a full time job for example. If their needs were met, I think they’d work happily on optimizing tractor schedules and crop rotation plans

I would probably do my job for free if I didn’t have to think about retirement and keeping my house and filling my belly. I just like what I do and I find it rewarding. The problem is still resource allocation.

No, I don’t think centralizing power and central planning will solve this either, I’m just saying people will be productive even without money.
