Food is a necessity
What happens if the seller decides to quadruple the price overnight ? (à la OPEC but for crops)
If some country does 'sanctions' ? (like Russia or the USA when they can't just declare a war to a place)
or if the economy collapses and imports are expensive ? (imagine Venezuela, but the country is also not able to buy crops that work)
these crops sellers will own the Kenyans.
I wouldn't buy the crops if patents were enforced.
it feels like some SF novel (or the Washington Consensus, yet again)
Back in the days, China forced foreign companies to work with domestic companies to sell in China. And at least, they are independent on some technologies now.
