We don't seem to care much about giving people access to caffeine, allergy pills, corrective lenses, and in many places alcohol and marijuana.

Why is it a problem if there's wider access to these drugs? So far, afaik, there's been no long term major adverse effects, and especially I've seen no reports of adverse effects that extend beyond use of the drug (as has been the case with previously popular weight loss drugs that could injure people's hearts).

We're 5 years since fda approval specifically for weight loss and 9 years since fda approval for type 2 diabetes. That's a pretty good amount of time to find serious problems, although certainly many withdrawn drugs were on the market for longer, ex wikipedia says Ranitidine was the biggest selling prescription drug in 1987, but was found to be problematic in 2019 (apparently a new formulation is available as of late 2025!)

Sure, there are other ways to work on weight, just like there are other ways to work on allergies and exercises some people say are effective for vision problems. But we don't force people to give up pets or move somewhere that has fewer triggering allergens, we let them take allergy pills; we let people use eyeglasses or contact lenses or have their eyeballs adjusted so they can see; etc. There's a tool that's effective for many people, why not use it?
