I can get on board with a decentralised participation income system that artfully and with tacit consent from the tax paying electorate debases the currency in order to provide an income to people who contribute to society in a manner that is difficult for the market to monetise, e.g. looking after a disabled child or elderly parent, rehabilitating former convicts through community initiatives, various ancillary aspects of the health system, basically doing anything that the state would otherwise be compelled to fund by a society in decay.

People would be free to vote against such a voluntary system by moving their money into Bitcoin, putting a hard limit on the state's ability to pay out the income denominated in fiat, meaning if people want the system to exist they better justify it and design it well so that tax payers and higher earners consent.

This would be a more sane version of the welfare state.

But UBI is just bullshit.
