This works for all forms of agricultural products grow in the 3rd world. Farmers can earn more for their family. Problem is this has already been done in fiat. Why do it in bitcoin?
Farmers don't get a fair deal because they don't have the education to know how to sell their own harvests properly. For example farmers used to get something like .01 penny/pound Then it rose as Folgers grew up, then starbucks, and then we have today where there is a large fair trade market, which can still be improved even more, cutting out even more people. Soon the farmer is going to receive an order directly from the roaster. and the roaster can be almost anywhere in the world.
The innovation is when you make a cup of coffee, the technology advances perhaps to a point in 10 years where coffee is automatically deducted from our wallet which goes to the coffee roaster, who can now place an order for more beans..
The goal is to cut out the middlemen, perhaps, roasting beans will become a do it yourself thing
We don't need behemoth corporations, especially in a debt based system. They can and will squeeze the life out of the people and leave them destitute.
