In this case, you'd have people lining up for their mRNA shot absolutely freewillingly

And what about those who don't? Force them to get it? Force them to social distance? Force them to stay home? Or allow them to kill grandma because "freedom"?

It is synonymous though, and honestly, would actually be reasonable in this line of thought:

Maybe so. It would be hard to actually know who has it or not, and fuck some kind of gay ass "registry". Privacy is important, and privacy doesn't mesh well with detailed tracking of every citizen, obviously.

Though I'd say, it's absolutely possible to identify people who are going out in public with symptoms and tell them to go home, somewhere alone, somewhere with other sick people, or somewhere with people who don't mind. It'd be no different from the police booting someone out of Walmart for indecent exposure. They address it when they see it, but don't go to nude beaches and start making mass arrests.

There can absolutely be a middle ground between freedom to do what you want during an alleged pandemic and a medical tyranny. It shouldn't be a free-for-all if an actual deadly disease appears, but we don't need to lock down the world and force inject people, either.

The option shouldn't be "let me do whatever I want, or you might as well shoot me". It should be "let me take my unvaxxed grandma who isn't afraid of dying of the coof to the empty beach near my house". That's freedom properly understood.

if I understand right, around half your country, and all of blue cities, would gladly feel righteous and just again, drowning in tingles as they are better than those grandma murdering freedom lovers, so this thought experiment may materialize faster than anybody of us would want.

I think it's less than half. They like to make it seem like it's half or a majority, though.

And the difference would be that, while in my thought experiment the coof was deadly and the vax is safe, in reality, the coof is benign and the vax is deadly, so they can feel how they want, but it's not just and righteous to reimplement their bullshit.

Their feelings don't matter. Just like feelings don't matter in science, feelings don't matter when determining the right course of action in government. It's about what is true, and that CAN be discovered.
