That's an extremely silly take.
It's like you think this is about compliance rather than, you know, ending the pandemic.

Since it's too late to genuinely fix now, the best thing that can happen is shaming stupidity. Applying evolutionary pressure to individuals that take bad actions is an incredibly good idea. Making the unvaccinated modern lepers is good for society as a whole.
It's not compliance, it's acting rationally. Politically, I'm not even very far from the group most adamant about not getting vaccinated (card-carrying anti-Democrat, here), yet I still acknowledge that not getting vaccinated is an incredible act of stupidity. People who celebrate stupidity instead of acting rationally in times of plague should have evolutionary pressure applied.
It's too late to turn back time and fix the pandemic by forcing them to act rationally, but by applying pressure to prevent them from having success in society, we can make them much less likely to be around the next time this happens. The society of the United States has been doing things like this since it began quite successfully, and it would be ridiculous to stop doing it now.
