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.
