I have a feeling natural selection will take its course at the level of nations, with nations that do protect their weak surviving and the ones that let profit extractors exploit and abuse theirs dying off.
This is an exaggeration intended to provoke.
>allow natural selection to take its course
This is hideous.
>I'm empathetic to the struggle of addiction
You are very strongly implying that this is untrue.
Well, we do want to protect the weak (that's a function of society, after all), and I'm totally okay with removing infinite scrolling from social media apps (or "crippling freedom" as you put it). I don't see any significant benefit it provides to individuals or society. Indeed, it has a negative impact on both. So it sounds like a win/win.
