We don’t have an alternative for oxygen. Our biology requires it. It is unrealistic to think we could do without, it’s science fiction. Capitalism is not something that exists outside of the human mind. Changing something that exists only in the human mind is of course very possible. It exists only in as far as we believe in it. If we would no longer believe in it, it would seize to exist. We could go for anarchy as an alternative. Or communism. But perhaps these too are the old ways, and we need new ones. New fictions to believe in because we’re confronted with new challanges. Believing in capitalism has brought us to destroy our habitats. If we’d simply think 'The whole world is capitalist. Changing it at this point seems unrealistic", that is indeed a very defeatis attitude. That is not to say that I have the alternative ready. I’m saying in this new time we shouldn’t stick to old dogma, believing it is the only way.
