I think there's plenty of use for a computer in the woods, particularly for automation, telling time, etc. just not any task that requires internet obviously.
For example, imagine having a solar panel and battery connected to an Arduino that controls some sort of motor or pump and at certain times of the day it turns on and waters your crops. You could even use sensors connected to the Arduino to measure environmental conditions like temperature, humidity, and soil moisture.
Shhh, you'll attract the solarpunks and then we'll really be finding out all about the ways of low-tech and high-nature. Some of us have things to do today other than design low-watt high-flow irrigation.
Gotta beware those IR satellite cameras tho. Tunnels. For real privacy you need tunnels.
Also nukes, or someone's going to invade you before you're done.
But not ordinary nukes, off the shelf at your nearest military supplier. Those aren't really free, you know, and besides licensing issues you never know what trackers and backdoors are hidden inside.
