I generally don't think that's it's good or just for a government to collude with manufacturers to track/trace it's citizens without consent or notice. And even if notice was given, I'd still be against it
The arguments put forward by people generally I don't find compelling -- for example, in this thread around protecting against counterfeit.
The "force" applied to address these concerns is totally out of proportion. Whenever these discussions happen, I feel like they descend into a general viewpoint, "if we could technically solve any possible crime, we should do everything in our power to solve it."
I'm against this viewpoint, and acknowledge that that means _some crime_ occurs. That's acceptable to me. I don't feel that society is correctly structured to "treat" crime appropriately, and technology has outpaced our ability to holistically address it.
Generally, I don't see (speaking for the US) the highest incarceration rate in the world to be a good thing, or being generally effective, and I don't believe that increasing that number will change outcomes.
