This is explicitly one of the goals of replacing the current social safety nets with UBI.
UBI can't replace social safety nets. It's impossible. 12k for every adult is 3 trillion dollars, which almost always assumes cutting other programs. What about healthcare? I bet most would rather have comprehensive health coverage instead of 12k every year, but you can't have both. In the US we have neither.
You'd have to lose safety nets to make UBI work, financially. If you can show otherwise, do you mind explaining it?
