I was thinking about morality in global sense, like choosing lesser evil, which trolley problem is in it.s core. Is it ok to sacrifice some freedoms for the benefits of community? And who and why decides what is beneficial for community? When the situation is clear, more obvious and understandable, like war, much more people are willing to join the army plus rest of them are being forced (I know, been in a war zone) and then no one calls for their rights that are against war... you catch the point.
When you say that everybody has to decide if want to meet other people, not that easy as it sounds: I don.t get to choose with whom I will spend around 3hrs in public transportation every day, or with whom I am going to work so, not all unwanted contacts can be avoid.
Just to be clear, I am not advocating for force vaccination, just discussing some of your statements :)
