"Freedom" is another word, like "capitalism" that the vast majority don't understand - and they want it for themselves and not others. It's ok for you to not wear a mask or get vaccinated, but if I want to sit next to you in a crowded restaurant and light up a cigar? You'd have a problem with that...
I somewhat enjoy asking people to define "freedom" when they justify their selfish actions. 99% of the time they are describing anarchy - which, to be fair, does actually work for a few people - however would be a poor form of government.
