Money is a social construct. Public goods are traditionally funded by taxes. Dual to taxing someone would be to print new money for everyone except that person. We need to pay ourselves and take ourselves seriously.
If you want to persuade someone to give you food for some kind of token then that token has to be meaningful enough that the person with the food can use it to get something else for it... social construct.
I am just saying that governance is inefficient due to poor incentives and that we are free to do whatever we want in cyberspace, including experiments on how we can align incentives better in the real world. If those experiments prove successful then the tokens will prove persuasive.
