The idea that can not be used for something other than COVID is moronic, this type of system has been done in Marketing for a long time, Google knows this very well.

you can not have an anonymous system that also provides aways to trace back to individuals you came in contact with
it is impossible

that is with out getting into the ways to compromise the device to get the original Tracking key that all of the other tracking keys are generated from
You can afford to give up a few days of your privacy for that. Really, you can.
If that is all the justification you have, you have already lost the debate. That kind of justification can be used for all manner of dystopian programs. Authoritarians have been limiting privacy and freedom for centuries on the basis of safety.
Right now in congress the EARNIT act is attempting to use that very argument for the "safety of children" we all need to give up E2E encryption
No I completely reject your premise that because of safety I need to give up my privacy

For example should I have my every moment monitored because I might hurt someone? Should everyone have to have a BAC monitor on their cars so save people from drunk driving?
Just trying to see if there is any limits in your Authoritarian world
