So I am OK with retaining some state and capitalist structures as intermediate steps with the long-term goal of eliminating them once we develop superior social systems.

That’s like saying you’re ok with leaving a malignant tumour whose entire purpose is to infect the rest of your body in your brain because it’s easier than having surgery to remove it.

A system that by definition seeks growth at all costs is not a viable partner for change, never mind progress. Never will be.
