Arguably a better comparison would be food: Many people struggle with obesity, but limiting access to food is not really the way to help with that.

A counter example is alcohol prohibition in Islam: It worked and to this day to to a great extent still works, unlike failed American Prohibition.

There is abundant food in places without obesity epidemics. The problem is food policy in the US, not abundance.

Exactly, and likely the availability/affordability of nutritious food as well.

And to loop the analogy back – I don't think ubiquitous network reachability is ultimately a big problem; it's what we do with it: Social expectations around constant availability to respond, addictive/heavily gamified applications, etc.

Good analogy.
