“ I ask myself, if I am diagnosed with toxoplasmosis, would I want a cheap 60-year old medicine that wasn’t being actively researched and improved, or would I chose a drug that was being invested in and improved, even if my insurance company forked over thousands for it?”
Age doesn’t make a drug less effective. See: Asprin. Darapeim works, and it works well.
Don’t try to justify what is essentially unadulterated avarice.
