Exactly, but I still think those are two slightly different conversations. If we are talking about harmful habits at a more general level, I'll defend that we need to be very restrictive in those examples. Online gambling, alcohol use and such shouldn't be allowed to advertise, it should pay almost prohibitively expensive taxes etc...

But if we are talking about the individual, the one inserted in the society, which is temporally bound, the conversation changes. We have to admit that it isn't enough to wait for laws and culture to change in order for the individual to be able to protect him/herself. To be a functional adult is to recognize what's around us that is harmful and do our best to protect ourselves. This is why if people recognize the harm social media is doing to their attention and to their ability to be bored they only have themselves to blame if you don't take action, because only blaming the multi-billion dollar industry for the habits they exploit won't do much for the individual.
