It's also super easy not to use hard drugs, yet that's not a reason to stop restricting them.

If something's harmful it should be controlled.

I find it pretty hypocritical that the same people who push for e.g. legal marijuana would go for banning social media apps. Don't get me wrong, I use neither and think both are mentally, physically, and morally corrosive. I would not care to have either present in the community where I live, nor for my future children to use them.

That does not mean it is the province of the state to ban them.
