You don't consider "you're not allowed in any building other than your own house, the closest grocery store to you, or an emergency room" to be a massive curtailing of freedom? Because a lot of places basically said exactly that.
People that don't mind killing other people to improve their personal comfort usually end up restricted to their cell and the prison's yard, when the issue is correctly framed.
I don't know why people expect this particular case should be any different.
I mean, I don't know how you imagine a better society but in mine there's definitely no cars involved (and I say that as someone who really really enjoys driving)
The average car driver doesn't risk passing a deadly virus to every single other driver they pass that day. Crashes don't kill that many people compared to the number of kilometers driven each day.
