A driving license is a license is a certification that you've proven yourself capable to meet the minimum requirements to operate a potentially dangerous device, and more akin to doctor's license, lawyer license, etc. I don't think it's really the same thing.
My concern isn't really with "government can do $evil_stuff", but more in the general restriction of things.

That's the one that I've never has a sane answer to - anything the government might want to do in the future with a vaccine passport, they can already do now with the plethora of unique identifying information they have on you.
