UBI is not "paying people not to work." That's more like typical unemployment - when people find jobs, the benefit goes away, creating a disincentive. With UBI, the benefit remains, (theoretically) encouraging risk taking.
This is not "paying people not to work" - that is a bad characterization of this trial, but maybe an accurate characterization of the dole. It's saying: Here's your minimum money, go and see what you can do.
For a local business owner, it's a big deal to take on a full time employee. If they have UBI, it is not. This makes it attractive and less risky for employers to give a few hours here and there.
The project in progress, however, saw people leave their existing jobs to, get this: go back to school full time so they could improve their lot, have children, or start businesses.
[Instead they got the rug pulled out from under them ~1 year into the program by the new government after being told they could rely on the program for 3 years]
I know it's a bit of snark, but your take is a bit simplistic and hand-wavy.
