You'd be surprised how many "normal" people initially revolted against seatbelt laws and protested through noncompliance. Even the people who accepted that seatbelt use was safer, refused to use them because of the usual "The Government Won't Tell Me What To Do!" mentality.
"I will endanger my own life, just to spite the government that will never know about how I'm spiting them unless I die."
I can understand not wanting the government to decide how they live their life, who they can and can't marry, how they should identify, which bathroom to use, etc. But I'd think no-cost life-saving stuff is not a hard decision. Same with vaccines.
That’s one very stupid way to die.
