Maybe the key insight here is the pivot from prohibition to differential friction. By architecturing high activation energy for distractions (black UI, location blocks) while maintaining low friction for utilities, you've essentially created a "price spread" between productive and unproductive uses of the same capability.
I suspect we're seeing an inevitable arms race: platforms driving activation energy toward zero (think TikTok's frictionless feed) versus commitment devices manufacturing artificial friction. Perhaps the sustainable equilibrium isn't digital abstinence but rather carefully engineered friction differentials that respect our inescapable need for connectivity.
Homeless people can't get access to govt. services if they don't have phone or callbacks in case they next in line to receive benefits. The following guy documents such problems that seem so obvious in retrospect.
