To summarize a bit glibly, you're saying to be a good parent. Which of course is awesome, and it is important for people like yourself to explain how to do that using the available tools, etc.

I think the concern many people have is that not everyone, maybe even not most, are good parents. They are themselves addicted to their screens, sports betting, credit cards, etc etc.

How much of a "nanny state" we create is a fair question. Of course due to economic incentives the companies will generally tend to outsource the problem as "be better parents", and indeed the problems of digital society are not these games' fault or burden alone. But to me it seems we have to break the cycle somewhere, and regulating these apps more is a perfectly sensible starting point. We should have freedom, yes, but also need to make systems that match reality on the ground and don't fail under the lowest common denominator situation.

Edit: not to assume you were implying otherwise. Just that we should avoid the "well it's not a problem for me, just do <x>" error.
