Feelings are uncorrelated with accuracy. Last year, the US revenue was $4.7 billion [1]. The US population is estimated to be 342 million [2]. If we had no government, we could UBI everyone $13,742/year. This is the maximum we could UBI, and it is not enough to live on. But if you want roads, enforcement of food and drug safety, some sort of law enforcement system, national parks, at least enough military to prevent Canada or Mexico from waltzing in and annexing us, support for research grants, etc. then it's going to be substantially less than that.
