If you are 3-400+ pounds, quickly shedding 100+ pounds makes exercising MUCH easier, and the accompanying loss in appetite will HOPEFULLY teach you better portion sizes. Countless morbidly overweight people have tried for years/decades to lose weight, without success, and GLPs allow them to bootstrap the process.

Yes, CICO, blah blah, but overcoming food addiction by asking people to eat less is like forcing a smoker who wants to quit to work at a cigar bar or something. You can't just not buy food, especially if you have a family you have to feed.
