No... corporation and dividend taxes require companies to be making profit, and companies almost always need working employees to do that, and sales tax only exists when people buy things - that's not happening anywhere near as much when everyone is only earning a basic income. What did I miss? And let's not forget there are still all the other public services to pay for.

I can certainly see potential in the idea of UBI, but primarily as a means of support when it's needed, not as a spur to retirement at 35.
