Learning self-discipline the hard way rather than treating yourself like a naughty child being told off.

It's less mentally taxing when you know you can't visit a website compared to when you have to work to not visit it.

Yes, but that mental taxation is essentially unlearning a bad habit and why it feels so rough to go through.

I agree that if the sentiment of "but I didn't go on it" is the goal, sure, but it doesn't change the way you think. Breaking habits is hard and requires willpower, that's why most people never break them.
