Someone could create a market where problem gamblers can buy wagering power (the ability to risk more after reaching their own loss cap) from non-gamblers unless you force physical in person gambling with ID checks.
Gambling should return to being legal in Vegas and on reservations, 24/7 gambling anywhere is very problematic.
They can but most non gamblers wouldn't partictpate. Many non gomblers won't particitate because they might go to vegas this year and so want the chance.
your market idea makes no sense, and it could be outlawed easily.
Alcohol should only be legal in pubs and bars; alcohol in Disney World, on planes, and in grocery stores is very problematic.
