Eh, my problem is that it's a bit of a tragedy of the commons situation. Yes, of course it's the best case scenario for an individual if 1. we eradicate COVID 2. they don't need to get vaccinated.

The problem is if we allow that sort of mentality to propagate unchallenged, then everyone wants to be one of the select few who take on zero personal risk but see all the benefit of an immunized herd. And then you don't end up with an immunized herd and society loses, tragedy-of-the-commons style.
