Everyone in society would have been better off if I had been permitted that. America could have paid me and 49 others a million dollars each and come out wayyy ahead (since direct exposure tests will yield results way faster). Then a 3 month safety protocol and we're off to the races.
But I can make that choice because I am comfortably above subsistence. If I do it, you know it's because it's a combination of bravado, bragging rights, and this money I could survive without.
But if you actually allow the market to price this, the real price for the tester is approximately $10 in sub-Saharan Africa, and we know he's on below subsistence and is really trading his body for another few days of life. We find that doing this is abhorrent.
An interesting effect that inequality prevents us from Pareto optimal actions and improving the human race as a whole.
