You make some interesting points here, but I think your logic is fundamentally limited. There are alternative, imaginative ways to solve this problem that don't necessarily involve capital. In _The Dispossessed_ by Ursula K. LeGuin, for example, able-bodied workers are required to perform essential work like agricultural work and other "dirty jobs". Much like we conscript people in times or war, we could do the same with regards to needed work that isn't getting done.
