It cannot be piloted without an entire country being subject to it. The whole point is that ALL the lowest income workers (janitors/fruit pickers/nursing home workers/etc) can quit their job, causing a massive re-pricing of labor and re-allocation of labor.
It would cause lots of things to increase in price that are currently priced low simply because someone's parents happened to be from a poorer country that did not speak English, and so on and so forth.
Without that, the benefits of UBI can never be observed.

I mean, that's you changing the definition of what a pilot is. Have you looked into how they were conducted in those countries and how they determine success/failure?
I do not need to look into how they were conducted. Universal is a condition of universal basic income, without which the dynamics of the labor market cannot change, and hence the benefits cannot be observed.
Only once all the lowest paid workers (who ostensibly are doing their job because they have no other option) can drop their jobs and negotiate better compensation can the effects of UBI be seen.
