“I’ll be poor because I won’t have a job”
There are many solutions around this. Many who live off the grid make the money they need from their creative talents. If you can get an internet connection, there are many opportunities to work remotely.
Saying that you won’t have a job is just an excuse. With a small change in mindset, you will find many opportunities for yourself no matter where you live.
The other benefit of living off the grid is that your money goes a lot further than it would living in a big city. When you don’t have rent to pay and you’re growing & cooking most of your own food life gets a lot less expensive.
