And not all freedoms are equal. My freedom to drive on the wrong side of the road is lesser than your freedom to drive safely, so we restrict the former over the latter. Australians have chosen the freedom to live free of the virus over some temporary freedom of movement.
In Auckland (NZ) we are in probably some of the strictest lockdown conditions in the world, with schools and non-essential business closed, travel only permitted for exercise in a local area or visit to the supermarket, and mandatory isolation and testing for close contacts. Lockdowns are still viable here because we have been so vigilant and basically everyone understands the shared responsibility. That's how we earn that freedom.
