Yeah but that would be moving JUST for the land, no?

For most people the equation is cost, climate, work, amenities, doctors, schools, commute, landscape, views, LAND, so on and so on.
It covers everything. My house in town on an acre is worth $75,000 and then I have 5.7 acres farther out. My home has 3 bedrooms, a chain link fenced yard, a quiet neighborhood, etc.
I use roadrunner, though Google Fiber is trying to move into the area. The crime rate is low which is a big reason why we bought it. We actually have 2 parcels of land: the one we live on was 20 minutes to my work and less to town: the other one is 5 minutes to a smallish town. I have MS and my doctor is one of the finer neurologists in the nation, and he is 30 minutes away. My school district is one of the best in the state and Kansas ranks in the upper middle for the quality of the schools in the nation. I am not sure what amenities you want but Kansas City is not far away and it is pretty quick to get there by the interstates. Views. Well, Kansas is flat but there are nice bluffs not that far away. And, between us and town there is a park that has been called "The jewel of the Johnson county parks" and with very good reason as it is VERY large and the lake offers great fishing and boating. PArt of the lake is against forested bluffs and that part has been left wild except for a hiking trail.
When we bought the 5.7 acres it was a 20 minute drive to a town with enough work to offer and it cost us $29,000. It was cheaper because we knew piped in water would not be available for 3 years and a creek crossing was needed before a house went in: this dropped the price by maybe $5000 total or a bit more.
I grew up in California where land is both high and of very high agricultural quality, but almost all of it is priced as housing land. I did have to move to find something more affordable.
If you do not want to pay the prices in your area for good land with all the amenities, you might have to move to find better.
As for Salatin you are correct about him not saying what he paid for the farm or what he paid on rent. At the time it irritated me but I CAN understand not wanting to talk about personal finances. I ALSO decided that it did not matter, as when we cut our spending to what we were comfortable with we had $150 per month to play with and regardless o what Salatin had that was what WE had.
So, I got out the pencils and the papers and I put those college classes in ag management to work. Using my current base of knowledge I should be able to break even working land with payments of $150 per month, with my marketing skills being the restricting factor, and the land would grow far more than I knew how to market. So, while I looked for land on weekends I also sold baked goods at the Farmer's Market to increase my marketing skills.
Then I put a down payment on land with the money I had saved up at $150 per month and that was the week I got sick. Oh, well!
The land you describe Is out there, but I am pretty sure you would have to move to the areas that have it. I am aware that land in both Virginias as well as Florida is expensive.
