A lot of these methods aren't easy to scale (yet) and depend on the outstanding expertise of individuals. There are also various incentives and circumstances that work against it, depending on the country where you live: - you can't get loans from the bank because its not a proven method (applies to food forests or other types of agroforestry, not to organic farming anymore) - you need some time investment to get the operation profitable, can be as much as ten years for a food forest - regulations may prevent you from acquiring land, simply because the method isn't known - you may not get subsidy and / or tax cuts because you have a different system or produce different crops - the crops you produce may not always get the best prize on the market - you simply aren't profiting from externalized costs, hence you are less competitive An example of the last point: to support our meat and dairy industry, the Netherlands imports cheap soy from Brazil, which is produced by destroying millions of hectares of rainforest. This is a bit like fossil fuels (also used a lot in agriculture): it isn't sustainable and it is taking advantage of cheap labor and destroying natural resources elsewhere. If you want to produce meat or dairy in a sustainable way in the Netherlands without taking a toll on the Amazonian Rainforest, you will need a lot of land which is very expensive, and therefore you aren't competitive anymore.
