Average one-way commute in the US is ~30 minutes. An hour lost every day. 20 hours every month. Literally we are losing ONE DAY at the road every month. 12 days every year.
And its much worse than it looks: When you commute, you don't only incur a time cost. You spend cognitive energy - you have to navigate transportation, cars, people, you have to avoid hitting another car or getting hit by a car, catch the tram at a certain time, do various things just to be able to get to the office.
All of these have a cognitive cost. They burn energy and especially cost concentration.
Then you have to enter the office, say hi to peopl around, settle in your desk, and start getting into the work mindset... only to be interrupted by the stand-up or whatever other practice your place has. Or maybe you will just wander around and not do much until that stand-up or meeting.
ALL of these cost immensely for both people and organizations. Economic cost. Energy cost. Burnout cost.
...
Compare this to the situation when working from home:
You get up. Get something to eat and a cup of coffee. You sit in front of the computer. You are ready to work without all that cognitive and time cost.
