The question you ask at the end of your post is golden. No matter how much money we have, is it enough to buy freedom? That's something that everybody will answer differently.
For me making 2k a month would be plenty to live decently in rural Vietnam with my wife and have plenty of money to spare, but I don't need air conditioning, refrigeration or many modern amenities to be content.
Perhaps it can buy slices of freedom, but once a slice is had, the next desire arrives and a new slice must be chased.
A simple life doesn't take much, but it is similar to having enough money - is simple enough for us?
