At any rate, I'm not convinced it's so much a lobbying problem than appealing to a questionable public sentiment. How much of that sentiment is driven by profit and how much of it is driven by more mundane misconception is hard to tell (for me).

Not necessarily. Some GMO strains require less chemicals and make some of the tech redundant.
One trivial example is that Google, one of the richest company in the world, has been trying to build housing in its home town of Mountain View for 20 years. Last I heard, nothing had happened.
Don't prohibit GMO, just invalidate the patents and regulate the results. If everyone can select the seeds that are designed best downstream farmers and consumers benefit from the reduction of monopoly.
Literally the entire current farming industry. Especially the high markup “organic” segment.
Major economics changes in any industry entirely wipe out lots of participants. Investments in certain types of equipment no longer make sense, farms in particular areas stop making sense, etc.
