Would you quit the internet for $100.000, permanently.

Permanently, definitely not. There's just far too much to miss out on.
I'd certainly do it for a temporary amount of time, but even then it wouldn't be extremely long.

I have managed to go several months previous without internet, which starts off the hardest and then you eventually reap the benefits and then go back to the internet when you're less reliant. I suggest doing something like this, maybe even just for a week or so at first.
