it's true we can't go back to barter and trade but it's also true that with technology today, we no longer need currency to function. we're getting there anyway, by small steps. we're "disrupting" industries, putting people where they need to go, doing what they need to do, what needs to be done. uber, fiverr, etc.

things still need to be done and there's no reason why the people who could do it best and want to do it, will still do it. we can also tie jobs to quality of life, if we wanted to.
