That's also (mostly) propaganda. Farmers are very busy without having to deal with the side business of inefficiently growing their seeds and would buy anyway.

Not everywhere, even in the USA. I know there are small family farms that got busted for growing gmo seeds so it is worthwhile for some. Maybe not the big players.

If farmers would buy seed anyway, then why are companies putting effort into forcing them to do so?

[frostburg]

It's more of a measure against competitor sellers than against farmers.

An important, but little known fact about modern agriculture, is that _everyone_ buys seeds from specialized seed companies.
