I'd also stop working, though instead of working on a moonshot I'd go camping, work on my garden, and spend long days playing games with friends and family.
There is a qualitative difference between needing to spend 40+ hours a week to sustain yourself versus spending 0 hours. If one need to spend those hours anyways it makes sense to maximize the income from doing so.
It may take a generation, but I think most people would eventually come to the conclusion that the rat race isn't worth it when zero hours is an option.
