The majority of offices are located in the biggest cities >1mil population. Every such city has huge size and insane traffic jams, where people are wasting a lot of their lives. Regardless of my preference to work from office (some days I do want to see my colleagues), the sad reality of commute is going to be a major factor in preferring remote work. I do not want to waste 15 full days every year at sitting in traffic jam, or standing in a bus packed with people. And neither do most of the people with such option. Having an office in <30 minutes commute or even walkable distance is a luxury really, and very few people have it.
