> That’s where i disagree with your characterisation of the difference between chess and slot machines. It depend entirely on the person involved. Folks who can enjoy responsibly shouldn’t penalised because there are others who can’t.
Arguably we do have that with slot machines. If you want to go somewhere to gamble recreationally, you can book a trip to Vegas or Atlantic City. But we limit access because of the potential for harm. We don't let kids gamble, and I'm certain if every gas station was allowed to have a couple slot machines inside, we'd see a lot more people throwing their life savings away because their brains aren't wired in a way which lets them resist the compulsion.
There's a spectrum in terms of how addictive things are, and how much harm they do which we use to determine how much we as a society deem it is responsible to limit access to these things in order to protect people and society as a whole.
For instance, coffee is quite addictive, but it's not vary harmful, so access is pretty much free. Sugar is pretty addictive, but only slightly harmful, so it largely gets a pass. Cigarettes and alcohol are addictive and moderately harmful, so we keep them away from kids and tax them to make them more expensive and less attainable. Hard liquor is more harmful than beer and wine, so a lot of places restrict access to specific stores to make it harder to come by.
And it might be the case that some people can enjoy heroin responsibly, but it's so strongly addictive, and so incredibly harmful that we make it illegal to obtain it at all - even that means "penalising" the few folks who could potentially enjoy it responsibly.
I don't know where social media fits on that spectrum, but it is addictive, and it is at least worth considering how much harm is being done and whether we should think about regulating it.
