So if phosphate rock is mined, and none of naturally occurring radioactive materials are deliberately removed, then it is just phosphate fertilizer. That's OK?
No. Like many modern commercial practices, putting radioactive fertilizers on fields to grow foods is a foolish thing to do. There is
strong evidence that the primary cancer-causing agent in tobacco smoke is radiation from the phosphate fertilizers that was taken up by the plants and transferred to the lungs by the smoke. This radiation is taken up by food crops as well, but the effects of eating these radioactive foods is apparently not as harmful as smoking the tobacco. But is it safe? As we dig up more and more radioactive materials from the ground and spread it on our fields, we only add to the environmental damage we do. IMO, a much wiser solution is to use organic fertilizers, which is exactly what we use here.

Note that the product is not the same. Normal phosphate fertilizer is a solid, while that which has had some of the radioactive materials removed is a liquid with additional chemical additives. It is very likely that liquid fertilizers will be absorbed by plants in a different manner than solid fertilizers. Is is more dangerous than original solid fertilizer? I don't know, but it seems both are likely hazardous.

Do I have the problem correctly stated?
You have tried to minimize the impact of mining naturally-occurring radioactive materials for spreading onto our food crops, but that does not mean the practices are wise or safe. Also note by mining the phosphate rocks to produce fertilizer, there are radioactive by-products such as radioactive gypsum which are piling up in massive quantities. Here is a link which details some of the side-effects of producing phosphate fertilizers from mined ore:

Or did I miss some key point?
It seems you have missed the anecdotal evidence listed of plant and animal health problems after application of the materials. Dismiss that if you like, but those reports could indicate real problems which are not yet understood and/or acknowledged by the corporations profiting from the production and sale of these materials.
IMO, if we choose to ignore the ever-growing rates of cancer and other diseases in our society and don't keep working to reduce know causes of cancer such as radiation, then we deserve our fate. But I prefer to work to reduce the mining of radioactive materials as much as possible and simply leave them in the ground. Likely our health and the health of our environment will benefit from such a step.
