If I include things like Medicare, Medicaid, Social Security, Education, etc... all social welfare programs add up to maybe $1.5T a year. There are about 320M people in the US. Let's leave out anyone under 18 (23%) that leaves us with about 250M people. Assume that somehow, all of these welfare programs are dismantled to be replaced by a BI. It's totally politically unfeasible, but let's imagine it happens. That leaves $1.5T to be distributed yearly among 250M people, which comes to about $500 a month. That's as a replacement of all medical aid, all social security, all public schooling, etc... Proponents of BI cite higher numbers, and political reality means many of these programs will stay. This suggests that BI will not come about without a dramatic increase in taxation.
