>Provide others with a token that represents the group's value and potential as human beings. That is already non-zero (researchers are very valuable!).
If that's the logic, you can do that today without any cryptocurrency. Take a blank sheet of paper and write, "the bearer of this note acknowledges my value & potential as a human being."
Go and take that paper out on the street and see if you can trade it for other pieces of paper such as Euros, US Dollars, or real goods such as hamburgers. If your experiment works, everyone can have "basic income" just by writing affirmations on sheets of paper and trading them.
I'm not being flippant with my example. Warren Buffet can take a piece of paper and write, "the bearer of this note is entitled to a 1 hour lunch with me." Someone could take that note and sell it on ebay for over $1000. (A similar type of transaction happens everyday with celebrity autographs.)
There's a reason why Warren Buffet's piece of paper (scrip, IOU, whatever) is more valuable than your piece of paper or my piece of paper. Cryptocurrency doesn't solve that. Basic income is also not something that can be solved by cryptocurrency.
