If that's the main driver, then instead of forced WFH, let's do a blanket ban of cars. Not just commute to work, but force people to stay at home at all times. After all, we're ignoring all the other effects here right?
Tackling climate change is a step at a time. First, we support WFH. Then, we can move on to other things.
And yes- I would like to see a total ban on gas guzzling cars in my lifetime. I would like to see cities built around walkability, and ban all types of cars entirely in the city center. Etc. But it's a step by step process.
