Have you been tested? Every day? You can't confidently say you're not infectious when a large proportion of cases are asymptomatic, or very mild. By all means be gung-ho about your own life, but your rights stop at the point they risk other people.
It is really not how it should work at all.
Assuming everyone is infected at all times is both absurd and most importantly unworkable and counterproductive. The net effect is the opposite of what it wants to achieve.
Mature democracies should have the ability to carefully and responsibly limit some rights in times of great crisis, such as wars and pandemics.
