Yes, because it's a good product.

Farmer's can't afford not to use tractors or artificial irrigation either.

It's not sinister to develop a product that is better than the competition.

Right up until someone else makes a better product.

> Right up until someone else makes a better product.

Yes. A different seed supplier. My point isn't that it's morally wrong to make a better product. My point is that the way it's set up is that those who are in the position to make a better patented-product are in an unbalancedly better position towards the people who use the product to create something as fundamentally important as food.
