If there are people interact on your instance, then you have the ability to restrict their speech.
I think that focusing everything on UBI and dismantling all other forms of welfare are going to create massive inequalities in society that few people anticipate.
For instance, I wouldn’t be surprised if there are effectively UBI free zones in some major metros with decent economies.
