There is no evidence that the virus can be get ridden of.
> An unvaccinated person attending a public gathering risks other people's lives as well.
Because it implies there is no risk for the vaccinated to spread disease.
I'm not sure what you mean. Police would use force to stop a drunk driver from driving drunk.
What are the prerequisites of the applied force in the case of staying unvaccinated? What are the acts of volition that justify the force?
Your mind has been destroyed, and unfortunately there is no vaccine (remember, the definition can change).
This is not remotely comparable, banning driving would (for most people) require changing entirely your lifestyle.
Getting a shot require a couple hours.
Banning cars is equivalent to a full lockdown - useful temporarily if the issue is getting out of control, but despite working well, takes so much away from us that it's definitely not worth it long-term.
Banning drunk, unlicensed, etc. people from driving treats the issue more immediately without taking away ver much at all. Yes, drunkards won't get to drive, even if they're willing to risk it, so that's a negative effect for them, but society as a whole will gladly sacrifice that to protect everyone else (including them, even if they don't want it).
