That is asbolutely wrong.

Price discovery is the thing that tells people to make food. It is the thing that tells people to make meds.

It's also the thing that tells people to continue making and doing things that people need and aren't meds and food - like keep cleaning the streets, keep up basic sanitation, continue making the electricity run, etc.

I agree generally with what you say, but I think that the fed is not threatening price discovery but addressing a huge danger to it, which is an abnormal demand for credit. At all times there needs to be a certain amount of credit for people and business to function and in a crisis, demand suddenly spikes.
