Sure, and I think everyone's on the same page that you should be free to do that. The question is how the rest of us can best get back to a (mostly) normal life.
Just to be really clear, you're free to do what you want. And I don't care what you do.
What I don't feel is correct is to institute policy based on things that the CDC says are not effective enough to determine policy. Or to support intentional infection based on not understanding the illness well enough. The reason I don't support that is not because I care about what the people forcing infection do to themselves, but what they do to the people that need to support them (hospitals, going out when ill and infecting others who didn't sign up for that, etc).
That makes sense to me. I certainly agree that we shouldn't institute ineffective policy that won't accomplish our goals, and I share the CDC's skepticism of immunity passports.
