Here is why I do think it's an amazing idea and why it would work for developing countries.
The farmers grow and sell in a bulk to the middle man which then sells to consumers. Now the cost is very very different. Let me tell you some stats. The cost of something x as sold by the farmer is generally = 1y but when you buy it from the middle man it's 20y.
Yeah too bad it's not like that, and I can get you some number on that.
Milk sold directly from the farm, 30cents/l , milk price in chain stores, from 60-1.20, remember it's also VAT.
Wheat is selling right now at 250 euros per ton, the price of flour is at around 80 cents per kilo.
Higher quality pig meat is at 7 euros, if you're going to tell me the cost is 30 cents...
No, stop with these numbers, they are just wrong, at 20x nobody would grow that food in the first place.
Now the government might have to ;
1. Give free classes to teach them about cryptocurrencies and how they can be used to expand their business
2. Provide them easy loans to start it on their own for the time.
3. Have a good support system for them till they are able to understand how everything works.
What's the point of number 1? Two continents have managed to get out of that situation without any crypto, why would that be a stringent step? It isn't!
Notice a small supply of plastic waste there? Where does plastic come from? Its essentially made from oil. All plastic waste and plastic pollution littering the world is oil. There are methods to take that plastic waste and recycle it back into a fossil fuel. Which could potentially expand the world's fossil fuel supply, decreasing shipping, fertilizer, herbicide and pesticide costs.
Yeah, too bad you can't turn plastic into fossil fuel cheaply.
First, plastic makes a tiny fraction of oil consumption, second, it's hard as hell to even produce the fuel, and the cost is outweighing the price of crude by an insane margin.
Why do you think nobody is making gasoline out of coal?

If crypto currencies are used, there is a chance part of this price will be reduced, becoming more affordable for every farmers around.
Nice, now cryptos can get rid of bureaucracy, I'm not even going to ask you why and how this would be possible.
