Its not just the commute but the other things around the house you can parallelize e.g. during a zoom meeting and save time. Doing the dishes, laundry, working out, running errands midday without traffic, not having to go to the dmv on saturday. That really opens up a lot more time than just the commute. Its really an entire paradigm shift of changing work from a block of time removed from the day, to just a series of tasks in your job queue that has some home chore tasks as well that can be taken care of when its actually convenient. You basically become an hpc job scheduler. Thats way more efficient than the blocks of time approach with going into the office and not being able to do these things.
