While I share the sentiment, this feels like an extreme, nuclear reaction which might be irreversible. I understand the fatigue, and resentment, but if you are about to be a family, you are going to find that typewriters aren't the acceptable mode of communication nowadays, and that you need some money to raise children.

Even if you are already wealthy and don't actually need to work anymore, going off the grid completely is still the wrong move. There's a lot of ways to spend less time online, improve your privacy and reduce tracking.
