I've one caution for those foodies who seek the simple life for its rewards. I surely agree one could be happy with a patch of land, a simple house, some animals, and some organics, at least as long as there's a good library nearby and broadband Internet connection.
But, and it's a big but, emulating the Amish or reverting to the diverse farms of 100 years ago is not simple. One of the hidden prerequisites of such a way of life is a large family, or at least a close-extended family. In other words--when there's no social security, when you become a geezer you become dependent on your children for your support. That's true for the Amish, it was true in 1910 farm life. Large families seem uncommon these days. To the extent single women have taken up farming, they are particularly vulnerable.
Yes, we have social security these days. (Social security coverage was extended to farmers in the mid 1950's.) But the size of your benefit is somewhat proportional to the amount of income you report and the amount of FICA tax you pay. If a quest for simplicity leads you to minimal income, or minimize your income on the 1040, or to skip paying the full 14-15 percent FICA tax for self-employed people, then you're vulnerable in your old age. (Unless, of course, you spent years toiling at the keyboard and establishing your 40 quarters. Then you will benefit from the structure of the system, getting higher benefits.)
