Our environment/context influences our behavior. Saying, "well, technically any given person could ignore their environment/context and act however is optimal!" isn't very helpful.
This article is acknowledging the environmental/systemic/contextual reality
All the advice in the article is about what you can do as an individual, for yourself. And I'm critiquing that advice as essentially sophomoric.
I don't know what you're inventing "hyper-individualist" out of, and the article doesn't give any advice on any "environmental/systemic/contextual reality".
> The project of atomization is the great illusory emancipatory freedom layered over an ever-constraining normality, atomization allows only for greater normality to be imposed on an individual level, away from families, groups and communes which will potentially have a sturdy and stable enough leader to disrupt the process of modernity.
Noe that I think about it, I seem to agree with you: it does seem suspect that the solutions to problems induced by atomization would not involve collaboration.
First of all, all this stuff of "do you remember" is how the brain is supposed to work. Our brain stays efficient by forgetting information that is no longer relevant. Who cares what you had for lunch last week? Forgetting that is a feature, not a bug.
As for the rest, the "advice" is fairly random and vaguely insulting ("start to fucking think", "read old books", "understand that things die", "wake up entirely").
My advice would be simpler and more direct.
If you have a problem with internet addiction, treat that directly. There are many sources out there to guide you.
If you have problems with fatigue and depression, see a therapist. There are many potential causes which a trained professional can help identify and work with.
And if your main problem is anxiety, then mindfulness meditation has been shown to help in many cases -- lots of good books on this. There are many other cases where mindfulness is not going to be enough, and therapy will be required.
