That's true but it would be extremely expensive if not impossible to implement therapy for all the addictive people in the world (most people, including me). So we just have to accept addiction and then try not to deliberately encourage the more damaging addictions. So addiction to coffee is not great but it doesn't do that much damage. Addiction to cigarettes does much more damage so while we don't probit it we don't allow people to deliberately encourage it via advertising.

Addiction to coffee? Are there a lot of people for whom coffee is harmful yet they keep on drinking it? The only people I know who say coffee is bad for them don't drink it.

Obese people, on the other hand, continue to eat despite knowing it makes them fat and unhealthy. It's an addiction just like cigarettes and should be treated the same.

Indeed; gambling as a business model, be it betting apps or gacha games, relies on hooking in "whales" (gambling addicts) for most of their profits.
