COMMENT | I’m writing from Victoria, the Australian state that became, in 1970, the first jurisdiction in the world to make it compulsory to wear a seat belt in a car. The legislation was attacked as a violation of individual freedom, but Victorians accepted it because it saved lives. Now most of the world has similar legislation. I can’t recall when I last heard someone demanding the freedom to drive without wearing a seat belt.

Instead, we are now hearing demands for the freedom to be unvaccinated against the virus that causes Covid-19. Brady Ellison, a member of the US Olympic archery team, says his decision not to get vaccinated was “one hundred percent a personal choice”, insisting that “anyone that says otherwise is taking away people’s freedoms”.

The oddity, here, is that laws requiring us to wear seat belts really are quite straightforwardly infringing on freedom, whereas laws requiring people to be vaccinated if they are going to be in places where they could infect other people are restricting one kind of freedom in order to protect the freedom of others to go about their business safely.

Don’t misunderstand me. I strongly support...
