Because you don't have infinite willpower.

You don't need "infinite" willpower. You might even need very little once you've changed into a default mode of using your phone less. By the way it's still unclear whether ego-depletion is a real phenomenon AFAIK.

You will need more willpower than what most people have, and so the problem remains.

Now what?

I'm noticing that for me, simply disrupting the pattern does wonders. A background process that re-bans websites via localhost redirect in my hosts file every few hours does wonders, for example.

A bad habit I can fall into as easily as breathing is a problem.

A bad habit I have to indulge in some effort to perform, puts me in the position of needing willpower to indulge in it!
