There are many ideas of freedom, depending what viewpoint you look at it from. Covid rules protects the freedom of the non infected and at risk and population as a whole.
The problem is, you can't identify who the non-infected are.
Vaccinations don't guarantee you are not infected.
Tests do not guarantee you are not infected.
Having been infected before doesn't guarantee you are not infected.
Wearing masks and social distancing doesn't guarantee you are not infected.
Displaying a QR code on your smartphone doesn't guarantee you are not infected.
So, if you don't know who is infected and who isn't to a certainty, you have to restrict the freedoms of everyone. No groups in your "solution" are having their freedoms protected, because the individuals can't be accurately assigned to those groups with any reasonable degree of certainty. The person determined to not be infected today may be infected tomorrow in spite of vaccinations, prior infection or tests taken.
