GMOs also have an issue of exposing the once very inert system to black swan events, health or environmental issues.
Similar thing happened with pesticides. Before GMOs can be used we should at least test them rigorously for a couple of generations. But yeah, that stuff did not happen with pesticides, cars or anything else that now has huge externalities.
GMOs would be used here to limit the amount of energy derived (carbohydrate) with regards to nutrient density.
Also, for what it's worth, part of the plant biomass used to feed livestock is inedible by humans (think cellulose).
The only reason GMOs would exist for humans would be to improve the yields of most popular plants which are obviously not raised for nutrition but for taste. Almost every other plant in the world is produced in such minuscule amounts compared to soybean, wheat, maize and rice that there's no need for GMO.
Governments and non profits are free to make GMOs that are available to all without IP issues, too, as has been done with golden rice.

I'm no expert on the issue, but from what I'm aware this is not true.
At least in the EU it seems there's now largely a consensus that non-GMO plants can't be patented:

There are still other IP rights that can apply to plants, but patents are a very different beast.
From the US Patent Office:

As just one example, the University of Minnesota got $6M in payments for their patent on HoneyCrisp apples before the patent expired:
E.g. the increased CO2 may be causing the bulk of the plant to grow bigger while the overall production of nutrients remains stable (nitrogen-limited ?) resulting in a lower concentration.
Adapting fertilisers might improve this. Or not.
I'm curious if you support the solution of allowing human population to decrease by encouraging fewer children.
