I hope we can avoid being this divisive with vaccine passports, if they actually come into play. That said, one side or the other will likely become dominant based on what people want to happen. Hopefully, we'll be able to get the virus under control to the point vaccine passports won't be necessary.
I think there’s several different reasons for vaccine passport pushback. Definitely not a singular position. For that matter, even the use of one isn’t a singular thing. Crossing international boarders, going to an 80,000 person stadium, attending a movie, or eating at a restaurant are all very different.
Proponents of a passport all seem to share a common goal at some level. To create a controlled group that can do an activity without any mitigation measures being used. Not stated, but implied is that this is desired before community spread is reduced.
For international borders, this makes sense. Those are different communities. They will likely control spread at different rates. Hence, anyone moving from worse to better being asked to prove they’re safe.
Inside and outside of a restaurant isn’t really a different community. Those use cases are all a tacit acceptance that special measures are needed to make them different. That the outside community isn’t going to control spread fast enough or ever. Lots of the pushback is that an end state, or even a prolonged time where we’ve created vaccinated people in constant contact with high spread isn’t a tenable solution. It will break down if it continues for to long. Which means we either solve spread and don’t need a passport within a community or we're just waiting for the next disaster variant to emerge. Hence, better to devote resources to vaccine hesitancy for a permanent solution.
That’s before pushback around the concept of tracking or databases or the act of providing proof to everyone being disliked. Also again separate from implementation questions on passport robustness, value, fraud risk, things with different implications for those different use cases.
The desired goal is a nice one, to be able to get back normal now sometimes. It’s the rest that’s more questionable.
