Capitalism does not “collapse” with 0 or negative GDP growth. I don’t know where people got this idea. You only really see any sort of “collapse” if the social structure breaks down - the basic behaviors of trading continue even in extreme crises, insofar as a society operates with property assigned to individuals like that. Not counting “bubbles” and such as a “collapse”.
What do they “make”? They control for the risks in social economic interaction with potentially adversarial parties. Ethereum is proof of stake, it doesn’t burn up tons of fossil fuels. And the contracts aren’t subject to human interpretation after being authored, they’re deterministic at the protocol level (save for the entire network deciding to revoke the contract).
Why are you making fundamental mischaracterizations of the technology while acting like an expert? What you’re doing is dishonest.
