What is your evidence that UBI reduces people’s contribution to society? If you’re referring to people not “working” in the traditional sense, not all contributions map nicely to economic output.
Exactly, the UBI would enable people to be paid for often non paying contributions like open source contributions, keeping park lands clean, creating educational content online and lots of other things. If I was paid a UBI I would still spend most of my time contributing but I would just do the things I see value in without having to worry about how will I make someone pay for this.
