My preferred solution would be to subsidize tools that allow people to better identify and resist compulsive behaviors. Apps like Opal and Freedom that allow you to monitor your free time and block apps or websites you have a troubled relationship with would probably see more use if everybody was given a voucher to buy a subscription. Funding more basic research into behavioral addictions like gambling, etc (ideally research that couldn’t be used by casinos and sports gambling apps on the other side). Helping fund the clinical trials for next Zepbound and Ozempic.
