Is this a 'how can we do complex production without capitalism' question or a 'how can we motivate people to do work without capitalism' question?

Former: Catalonia ran entire industries while at war. Something needs doing and it isn't getting done? Volunteer, find people to help you, etc.

Latter: I dunno, ask your mom how she cleaned and fed you for decades without financial compensation.

Bonus: a significant portion of drug research at least in the US is (or was anyway) funded by the US government, so capitalists aren't exactly doing all the work themselves.
