you can grow your own food, drill your own well and build your own house no money required. Now I agree that money helps it to move along and enables you to increase your standard of living. I'm just saying that as long as you have freedom the money will follow.
All of this is true but let's see how alert you are: just because no money was spent in the activities you provided above, were there costs involved [assuming the drilling equipment, and everything the goes into operating it, was paid for...same goes for the seeds and fertilizer needed for your crops and stuff for your livestock]?
