I agree that you can make the case that proof of antibodies should be treated like proof of vaccination. I can't see the harm in that and think it's a point worth bringing up.
I am more open to this than getting a vaccine, as my wife and I were infected before the COVID mania had set in (doctors couldn't tell us what it was). If I get a vaccine with a variant, how well will I fare as I'm in stage 3 heart failure? Check me for antibodies. That seems fair.
