I certainly don't understand but there is no need. The mechanism (provided it is legal) isn't really important.

We need work, to earn enough to survive and have some quality of life. It must feel like you've contributed something useful and society rewarded you reasonably for it. Others will have to do work for you or it wont work. If there is no money for that it cant work.

I think 100 years before things get truly silly.
