Our modern lifestyle is extremely different from the lifestyles that shaped our evolution over millennia. You can't just pick and choose to what aspects you apply the naturalistic argument.
At all time in history before the industrial revolution? You worked at home, which was right next to your field, or in front of /under your home. Commuting to work wasn't even an option ; usually only merchants traveled.
The weird situation is when you have to move away from your family in unfamiliar cramped apartments just so you can work in a factory nearby and perhaps send them back money. It's not "normal", it's rather abnormal but cities have adapted to this abnormal situation. The trend to economies becoming 100% services is helping to bring people back to ancient normality.

No we should be working to make residential areas more social and turn them to mixed residential/commercial, just how it used to be (and still is in most of europe). Offices are a relic.
This is actually going to happen spontaneously as soon as everyone has 4-5 neighbors who also work from home. It's a matter of time
