Because “farm Inc” has a massive horde of wealth, they can stamp out competition by either buying them out, cutting them out, or driving them out of business with prices a small farmer can’t handle.

This literally happens every time a market is poorly regulated and businesses allowed to grow too big. It’s the natural end state of capitalism.
