The problem isn't GMO, the problem is the type of changes big agritech is making.
Take, e.g. Clearfield Rapeseed: It's a herbicide-resistant strain, non-GMO, bred by BASF, and resistant against Clearfield, another BASF product. Thing is: Rapeseed is a brassicaceae, and they really like to exchange genes cross-species. There's tons of wild plants ("weeds") that are brassicaceae, in fact if you don't happen to be growing it rapeseed itself is a rather nasty weed. Which means that once that resistance is out there that stuff can't be killed by stuff that doesn't kill literally everything. Brassicaecae seeds can also stay dormant in the soil for years, making it even more nasty.
My state's agricultural ministry got wind of the stuff, quickly decided "that's insane we need to outlaw it", then quickly hit their head against the EU legislation which doesn't distinguish by impact on nature or environment or economy, but by GMO status. Instead they then flooded farmers with brochures telling them just in how much shit they would be should that stuff escape from their fields and other farmers demand compensation for loss of income etc.
The thing is: That stuff doesn't even make sense for BASF. "Sell resistant strain and a herbicide along with it" makes a lot of sense for chemical companies (and all big agritech are chemical companies), "spread that resistance throughout the whole environment" doesn't because who's going to buy their herbicide when it becomes ineffective. They really dropped the ball on that one, failed ecology 101.
Speaking of "we've got a hammer, where are the nails": Golden rice. The problem isn't that rice doesn't contain carotene, the problem is that there's people so piss-poor they can't afford half a carrot, onion, some garlic, and a spoon of beans with their bowl of rice. If you want a solution that is the problem to fix.
This is the kind of stuff actually modern agritech comes up with, problem being: It's not a thing you can earn money with as a company as there's no products to sell, definitely none you have a monopoly on, so those companies have literally zero incentive to research that kind of thing. Farmers don't have the funds (even in the west, they're getting squeezed by supermarkets and Nestle etc), but you know what, states already have universities. Give them a couple of fields to mess around with and you'll be surprised by what they come up with.
