People don't have the physical or mental ability to live alone. Their version of "alone" is a world where there are institutions that exist to protect their property, guarantee their transactions, and where they are supplied with a massive amount of high-quality manufactured goods. Paying for them doesn't make you somehow independent of society, it's the nature of society. You're trading bits of paper with government promises printed on them.
There's a big difference in living alone versus living in a big city though. Living in a cabin in the woods, as the example here, doesn't mean alone and cut off from everyone else. It likely just means a quieter, more self sufficient life.
Presumably if one is actually living alone in the woods they wouldn't be dependent on the larger societal systems like money, security, manufactured goods, etc. How would the get the money to start with without having a job that interacts with the outside world?
