I agree, but there are plenty of jobs that cannot be done in home office. During covid years I commuted like crazy (by train though) because I worked in a lab developing antiretrovirals. Even the project managers in biotech/pharma need to be on site especially in intense times (like covid) to be able to be in the lab. There are tons of jobs (isn't it 50%?) that cannot be done from home office. We need a strong public transport either way.

As a side note: The stupidest form of work is hybrid. So you still have to live relatively close to work to be able to commute, i.e. likely in an expensive metropolitan area, and pay higher rent prices because you need a working room, and the room is not fully tax deductible because you theoretically could be in the office (at least in Germany they deduct 6€/day for voluntary home office). It's a shame we don't have much more and much cheaper coworking spaces. They should be literally everywhere so you don't need to go further than 15 minutes.

Even if we assume everyone can work from home, people still need to go places for other reasons.
