I can see a few holes in this plan. Not because I am negative in nature, but because this is something that perplexes almost every large landowner out there; how to make their land make money. On paper it seems so easy, but it is anything but.
Easements: There is nothing easy about easements. A Landowner when he gets their deed either by purchasing or inheritance, with that land comes a huge set of rights that looks like asparagus stalks in a rubber band bundle. All easements do is
sell off those rights one at a time. The more that are sold off, the more rights lost, but more importantly, the more regulations that exist. This is even more so when these easements involve tax write offs. A lot of the easements have rules that counter other easements you list. For instance, leasing the land for power production automatically takes it out of agricultural production. If the land has been in ag production for years, that money has to be paid back for a series of years...up to 15 years!
Allowability: Never underestimate the power of jealousy. My farm sits on top of a huge hill and I was approached to have (3) mega-windmills put up here, but was turned down by the town for permitting mostly because only a few of us living on hills would get a lot of money for leasing our land. Building cabins, selling off power generation, etc, all require town approval and subject to restrictions and bureaucratic red tape.
Reselling land to a good steward: That will never happen, because as diligent as a person might be, as soon as a piece of land is sold, the ability to control that land is gone. I might sell to the most upmost buyer, but it does not mean that guy will not sell it. I have seen this so many times. Once a guy was offered 3 times more for his land then what it was worth, but he said he was giving it to his son. The day after he gave it to his son, the son sold it to the neighbor who had the house bulldozed within the week. My Cousin clearcut his land before the ink was dry on his deed.
Property Taxes: They are high, and every time you add a cabin, power generation unit, etc, they go up in insane amounts. Mine have doubled in only a few years time and now pay over $10,200 a YEAR! That is straight forest and farmland. I cannot imagine what they would be if I had a solar farm here, or had forty cabins. I could save money on my forest by putting it into Tree Growth, but then I could not put cabins in that forest either. See how the rules forbid other things from happening? And it begs the question, just who will pay for the taxes until these "improvements" can be made, and the portions needing to be sold are sold off? The permitting processes for this will take several years at least, so just paying the property taxes will eat into profits. Few investors will wait years and years to recoop their investment.
Location is also everything. Sure I have hundreds of acres that could be used to put in a solar farm, but getting that produced power out onto the grid will be costly. I do not live anywhere near three phase power which tends to stay close to industrialized and urban areas, just the places where hundreds of acres would be costly to buy. And even if there was land available, would it be allowed to converted into a solar farm by town rules? Ag stays ag because it is remote, and most people dislike change, especially if you will make money and they will not. So while it would be cheap to situate a solar farm on my own farm here, it would be costly to build a transmission line from my farm to the closest transmission line.
Here just about every single family farm has over 500 acres, so it is easily manageable by a family. I am not sure what the average is...perhaps 600 acres here, with some who only have 100 acres, while my neighbor has far more at 3200 acres. On myown farm (and NOT 3200 acres), here there are places I can improve, and I have plans for that, but overall it takes a fair chunk of land to be fully-farming...at least here. It is interesting because I always calculated that at 450 acres.
To me the whole overall plan reminds me of how Moldova was set up after the Russian's left their country, subdividing and splitting up the land to make it "fair" and it has been nothing but a collosal failure for that country; abject poverty to say the least. That is putting it mildly!
