Or we could just use the damn anti-trust regulations on the books to actually keep markets open and competitive. There doesn't have to be a worry that Monsanto will lock down seeds if they get split into different companies and some of those companies continue to sell seeds that aren't locked down.

I think any market segment without at least 10 comparably sized companies AND the option to just not transact with ANY of them is not competitive and will not benefit from any "free market" supposed benefits.
