The question here is whether to give farmers the freedom to choose to grow it - most will continue growing other varieties. Idk what uncontrollable regulations you are referring to, but no regulation will force you to grow something.
I also want to solve the problem and this is a great solution. It's worth enacting it, unless you have a better idea - children have been dying, die right now, and could continue to die if something isn't done.
