I think the UBI argument is that the cost of those shit-digging jobs will have to significantly rise to the actual price of finding someone willing to do them.
If I have to do work or starve, maybe I'm willing to dig shit for $15/hr.
If nobody has to do work to survive, suddenly you have to shell out $300/hr to motivate someone to do it.
