If I have to choose between a society where 11% of the population does some pointless work (and anything that doesn't pay at least what could be consider a 'basic income' is pretty much pointless) or one where 1% does amazing stuff in their spare time, and 10% does nothing. I'd prefer the latter.

Don't see how criminality would increase with basic income, if anything I'd expect a decrease (fewer people in hopeless situations = less crime).

Part of the benefit of a UBI is that it permits us to give harsher penalties to criminals because they can no longer use poverty as an excuse. I'm all in favor of cutting off UBI for criminals (temporarily or permanently depending on the severity of the crime).
