Of course, but the users can’t be trusted to stay away from something designed to addict them. Only real solution is regulation, although the how is still a big question mark.

I would ask, where is the line drawn between 'enjoyment and addiction.'

Is it the harm provided? Then what do we count as harm, and where is the line.

IE, There's no one stopping me from eating unhealthy, IE sugary foods, which are heavily addictive. I ride a motorbike, and I'd consider myself addicted to that, and it's got a high chance of harm, but we don't ban those. Ditto with gaming, social media, hobby XYZ.

I personally think the freedom to choose your vice is reasonable.
