I am free to avoid being forced to wear a seat belt. I can take a bus. I can take a taxi, I can ride a bike or I can walk.
I define freedom as having choice. If I do not qualify for something because of the choices I make then I am totally cool with that. What is important is that I have a choice.
Requiring seat belts is akin to requiring age of 16 or a requirement to pass a test in order to qualify to drive. I have a choice therfor I have my freedom.
how do you define freedom? Getting your way every second of everyday and never having any personal responsibility for the choices you make? Being free from any rules you disagree with?
