"provide for their needs"...? What do you mean? Sure, many gamblers don't have a very stable economic situation, but you're implying that something like UBI would suddenly stop people from gambling or what?

And then there are those of us for whom gambling is not a need. And I think it's problematic to regard any unnecessary activity, especially one that's a known focus for self-destructively compulsive behavior, as a need.

Heroin's a pressing need too, when you're addicted.
