> What problem does a domestic vaccine passport solve?

The same problem the Yellow Card [1] solves. Right now, I have a New York State electronic passport and a CDC paper proof of vaccination. The former works in New York City. The latter works across the U.S., at least now. (At least, it worked in San Francisco and Atlanta.) If I travel abroad, I may need to get the latter re-certified since it's trivial to forge and not independently verifiable. Having a single, authoritative document fixes all this and makes socializing and commerce more frictionless.

If we don't want to go into another lockdown when the Delta variant hits, we need to be able to isolate the vaccinated from the vulnerable. The former can continue mixing and mingling with reduced (though not zero) risk of causing a flare-up. The latter, I don't know, ideally they'd stay home but we know that won't happen.

I would bet a huge personal sum that if there were a federal legal guarantee of no vaccine passports, hesitancy would evaporate overnight, and every single SMART health leak and backdoor regulation to enable them is creating an increasingly hard core and radicalized resistance movement.

Yellow card is for some international travel and school enrollment. It is not a vaccine passport, so while I appreciate engaging the question, it's not clear that this is the same use case. Nobody asks an adult for their measles vaccination status in a normal domestic interaction like a concert, train, office, etc.

I think most people should get vaccinated and we can all move on with our lives, however, I also think a generalized vaccine passport for domestic use is an abomination with inevitable and horrific consequences, and so I am trying to get a sense of what the sincere case for it is. If it's just leveraging the crisis to institute bureaucratic social controls, I'll be the most reasonable man on the barricades.

We need a better "why" that is actually true, and not a cynical "noble lie," (like masks/no-masks was), because when you actually get off the internet and talk to people, it's the percieved lies and the attitudes of the people who tell them that are creating the hesitancy.

If a covid-unvaccinated person goes into a stadium or bar full of covid-vaccinated people, what is the effect? The only way the shots get more traction is with a clear and honest answer to that, imo.
