* If apps detect compulsive behavior, they could go dark on your phone for a day/week/month/year
* All bets could have delayed payoffs (e.g. greater than 10 minutes [0]) to avoid optimizing for a quick dopamine hit
* Apps could be linked to a credit score/measure of financial health and allow larger bets for people with higher credit scores, or they could stop you from placing bets if there's evidence of negative impacts on your overall financial situation.
In general, the question of: how can we let consenting adults take risks that they find pleasurable (drugs, sex work, gambling, free diving, etc.) while also limiting the worst harms and/or protecting the most vulnerable people, is under-discussed relative to its importance, IMO.
E.g. Dana White of UFC appears to have a gambling problem, but maybe with how much money he earns it actually isn't a problem - but what if it at some point it gets out of control, and that is hidden from friends or people that care about him - and where that loss of control could be hidden from sight, kept secret until it's perhaps too late - however that looks?
