I don't think your approach of continuing to keep the existing parasite within our body is preferable to isolating and excising it.
“I don’t think your approach of continuing to keep the existing parasite within our body is preferable to isolating and excising it.”
I understand, but you must consider the practical consequences of trying to physically excise the parasites when half a state is filled with them. We are a nation of 300 million people. Forcibly relocating half (or even a quarter) of them would result in one of the largest social upheavals in world history. Are you ready to do that? We are in big trouble, either way.
