It's not a permanent lockdown... just for a few weeks (so far)
It requires a lot of privilege and disconnect from the average person to support a lockdown two years into this.
The difference is that lockdowns here were a lot less strict. It was still possible to go to the shops for example, and people in critical supply chains (e.g. food, medical) could still work. Precisely to avoid this kind of issue where people are running out of food.
