Most of these are not ran by the government though. Thus their use is not mandated.

In libertarian circles this is generally spoken about as the `non-aggression principle`.

I in no way think that a proof of vaccination system put together by private providers, coupled with businesses' choice to check vaccination status is wrong. I do think the responsible thing to do is somewhere along the lines of self isolating to either being vaccinated or having an antibody test.

My objection is a government orchestrated vaccination database with mandated use in private businesses.
