In cartoons you'd have this concept where someone is sawing away with great energy on a branch while sitting on the dead side of the saw. This is that concept, but on a much larger scale.

If people want to build stuff they can, they just may not be paid for it. But if we don't need to pay anyone to do anything then it also doesn't matter that you aren't being paid, as you'd have all you need, and you can spend your time tinkering away on low tech/cottagecore enterprises like designing an ASIC or making bread.
