Step out of your bubble and think about all of the people making the goods you order, maintaining your roads, construction workers that fix your home, the workers at the grocery store, the person that delivers your packages, the warehouse workers, etc etc etc.
The world runs on people being physically present working jobs that can’t be done from home... that must continue so that you CAN work from home. Until robots can do those jobs, it'll always be the minority that works from home.
If you reduce the need to maintain both a worksite for people and a home, while you will increase the need for labor to maintain/service the home and supporting infrastructure somewwhat, it will probably be less than the reduced demand for labor to maintain and service the worksite. The initial effects of a large scale shift to telecommuting is going to include a lot of net physical service/maintenance/support jobs lost.
Step out of your bubble and think about what it would mean if 40% of Americans worked from home full time.
It can be done, we've seen that, now people are running the numbers and seeing what that means. Pre-covid it was something like 3% that worked from home at least half the time.
If 3% turns into 40% - or even 20% or 6% - that starts to change things.
The whole WFH discussion is an upper-middle class discussion. Low income workers don't have the option of working from home.
Remote collaboration tools like GH have been crucial for remote work for software developers, but that's a really small slice of the pie.
