No there isn't, you're also ignoring so-called third-hand smoke, which consists of smoke particles that attached to clothing, hair, skin, and inanimate objects. Third hand smoke can linger for extended period of time and is known to cause similar problems to both first and second-hand smoke. Just by existing, smokers are literally putting all of us at risk. https://www.mayoclinic.org/healthy-lifestyle/adult-health/expert-answers/third-hand-smoke/faq-20057791
Same goes for fatties. They make all of us worse off. There are literally so many fat asses in America, that fat people literally constitute a larger customer base then healthy people. Fatties exert their influence over the food supply and restaurant industry. They create a demand for more unhealthy food and more processed food. It's reached the point where even if you want healthy food, you need to go to like a specialty store or a farmers market or something. Fatties are a public healthy risk to us all.
I can actually agree with health-totalitarianism, because I eat healthy and have worked out (a combination of lifting, jogging, and biking) almost daily for 10+ years. I don't smoke, drink, or play video games. If we're going to ban going out in public with the flu (COVID, giga flu, super aids, call it whatever you want), then we should also ban people from being low T, pink haired trannies that live on Starbucks and prozac, because those people certainly aren't healthy, and their poor health does actually affect the rest of society.
Also, I'm wonder if you've heard of HIV/STD decriminalization, and what your thoughs are on it. HIV decriminalization, is the idea that people should not be subject to criminal charges if they fail to disclose HIV status to their sexual partners. The arguments is that these people feel targeted and discriminated against, and that modern treatments for HIV mean that HIV now has a relatively high survival rate (still, much lower than COVID, however).
