I would be very happy if my government did the same. What a relief it would be! It's a public health measure, like public sanitation requirements, and driving a car that meets safety requirements. Unvaccinated people should be free to do whatever they want, short of risking infecting other people. Your freedom ends where your fist ends and my nose begins.
I see this used every time, if you pay close attention to the phrase you will notice that it can literally be used every time by every party.
There will be people thinking that you can't limit their "freedom" because a vaccine is out there at this point and those who fears for their lives can take it and forget about the virus (in most cases).
There will be people thinking that unvaxxed people should loose their "freedom" because they apparently have an increasing probability to infect others (which in most cases are vaccinated and would get a mild infection in most cases?).
I personally don't care about my unvaxxed friends, I hang out with them as I've always had and I do respect their choice. But I am biased towards individuals rights than "public health".
