I think way too many people would notice that only-vaccinated people are dying. I mean think about the rate of vaccination too if it started killing people short-term... that's like > 100 million dead. Even Mao Zedong would blush. Also big pharma doesn't make money off dead people; much more profitable to have lasting side effects that require drugs. But I mean... that's the rub. In an actual emergency, ala Ebola or, God-forbid a super-contagious Ebola (e.g. airborne or something), I think we would need some authority in position to keep the crazies in line. That's the main difference - a lot of people figured out early on that covid wasn't some airborne space AIDS virus and they'd probably be fine. The mortality was never significant, the average age of mortality never dipped below life expectancy for men or women... I think were it killing/crippling young/healthy people then everyone would take it much more seriously. So idk, on the one hand it opens the door to concentrating power to the state, which pretty much always ends badly. OTOH if that power is used judiciously and responsibly it can be a boon to getting through an actual emergency. Your general concern is relevant, but I think your specific scenario is farfetched. Also I've read that the delta variant is weaker. I'm glad DeSantis put this particular legislation in place because I will not have my kids vaccinated for this. They're like 100x more likely to die on the trip to the doc's office for the vaccine than to even have complications from covid let alone die. Then again 2 years ago I would have thought shutting down the world and having large swaths of the population clamor for experimental treatments over a virus that kills old people would have been farfetched.
