We don't ban alcohol, videogames, twitter, tv shows, or buying excessive amounts of food, despite a giant number of people in the US suffering from addiction to those. War on drugs was a failure.

At some point, you have to draw a line at where you take personal responsibility. The utility to those who can use those things I listed above responsibly outweighs the potential danger and plies of those who use "addiction" as their primary argument for bans (aka I have no self-control, so you should not be able to use those things responsibly either).

I am not saying "let's make heroin recreationally legal, just use it responsibly", since both utility and danger are gradients, and for heroin they are of very dubious value. But for something that has no physical addiction component at all, like videogames or facebook, I am sorry, it is on you.

And please, no pedantry with "I get hits of dopamine when I browse my FB feed, so it is a physical addiction too!". This is not what physical addiction means in the context.
