It’s dangerous to go full off the grid, but in reality it’s never complete isolation. In Leave No Trace/My Abandonment (based on a true story) the father relied on disability checks to buy goods and educated his daughter using encyclopedias… In Walden Thorough is living alone in a remote area, but it’s not like he’s completely cut off from the benefits of society and has visitors somewhat regularly. I think there’s a difference between trying to minimize the brunt of society 24/7 vs going full isolation.
