What YOU do in the privacy of your house/apartment/whatever is YOUr business but when you interact with others outside your house/apartment/whatever then yes you should be told. Look at what happened at State of the World. No one was really enforcing local legal requirements.

I have a right to feel safe when I go to a WordCamp/local meetup. You not wearing your mask and been vaccinated, makes the chances of me being infected……..a lot higher.
