Zardiw, The benefit is in your number 1, and fixed so the chance that
positive won't ever transmit it to another is minimized, or eliminated.
If not tested and caught, under your 'no testing' regime that person could pass
it to others, and on and on again under your proposed no testing regime.
Put all positive tests together and you have a huge benefit.
I don't understand why you can't seem to accept that.
