It is certainly better than the status quo. Don't underestimate the effect of simply making something illegal.

100% agree. The 2007 smoking ban in the UK totally transformed the landscape here, and yes people could still go home and smoke or whatever, but that ban has made a huge and significant change to health and thinking about smoking over the last 20 years. We need to do the same with social media and recognise that it's likely to be seen as toxic as smoking in a few years time - if not already.

Yes, the effect of prohibition was enormous. Same with America's War on Drugs, that had a massive impact.

Probably not the impact you're implying though.
