Eh? We restrict activities that have negative externalities on the people around you all the time. To name a few: anything that creates pollution, smoking, excessive alcohol consumption, even having ridiculously bright headlights in your car.
Most of those things are restricted when they actually harm people NOT before. You are not restricted from consuming alcohol unless you go out and drink or do something else under the influence. You are not restricted from smoking unless you do it in a place where the smoke cannot be avoided. In this scenario you'd be demanding someone stop smoking while walking towards the smoke.
Lastly, I'm sort of done convincing people like you. I no longer care what you think. I and many others are going to move on with our lives. What are you going to do to stop us?
