Farmers can get extremely attached to one piece of land and one farming method and any attempts to shift the incentives in the system and make some types of farming or locations move on is portrayed as a systemic attack on farming and the end of the world.

Everyone appreciates the farmers, some farmers just don't seem to appreciate the harms certain types of farming put on everyone else and the ecosystem, and they'll hide behind how essential calories are to protect their interests.

You're aware the farming lobby is one of the strongest in many countries right? They're not under-served politically. Farming is one of the most subsidized industries.
