Everywhere you go the good land capable of providing such an off-the-grid lifestyle is already developed and is too expensive for a person such as yourself to purchase. The undeveloped land is usually worthless garbage, unsuitable for farming.
Even if you were able to get your hands on a good piece of land the sort of money you can earn with it without using modern methods is very limited. With farming you'll be competing with highly mechanized farming methods, while you use muscle power. Even nominally organic farming is highly mechanized these days, as 'organic' is pretty much just a buzzword to trick hippies and ecotards into paying 50% more for crappier produce. Ten years ago you could've made a go of it (assuming you already had land) but now? Nope. Muscle farming won't even earn you enough money to pay your property tax.
If you are intent on doing this, and are lucky enough to find good land that you can afford, you absolutely must choose a manpower intense-cash crop - something that earns a lot of money and has yet to be mechanized. Grow your own food on the side if you want, but if you intend to make a living by selling something like milk, eggs, grain, etc, using muscle power, then you're insane.
