Farming subsidies etc are the reality in high-income countries like UE or USA. But UE doesn't really *need* GMO because it can produce huge amounts of cheap food already.
GMO is needed in the first place by low-income countries in Africa and Asia, which still experience famines or vitamin deficits in 21st century! And here you have Greenpeace "heroically" destroying Golden Rice or Bt brinjal crops for the sake of... "purity" and fanatics like Vandana Shiva.
Obviously, a mutagen is like a bulldozer - it can modify a dozen of genes. Can make the plant more sweet, or more poisonous. But we don't care as long as the result is sweeter or bigger or whatever we like.
Then we discovered gamma rays, which do the gene splicing even better. New varieties of tomatoes, apples, potatoes, wheat etc etc. All produced through 20th century using mutation breeding.
Actually, Non-GMO Project maintains a whole list of plants that are "high risk" of being modified using CRiSPR (which they call GMO). The funniest part however that for many plants they *cannot* in any way distinguish them from non-CRiSPR (non-GMO as they call it) plants, yet they speak of "risk" and "contamination".
> No matter what a classical plant breeder does with tomatoes, you can assume its safe for anyone with a peanut allergy to eat them
You cannot make this assumption due to random mutations. If prolamin protein appeared in peanut, it could appear in tomato as well.*
With CRiSPR you can be pretty certain that nobody will put peanut cupin and prolamin proteins into tomato just to cause allergy in people.
* obviously probability is close to zero due to different evolutionary paths
