Like the parent, I also really like my commute. It's 40 minutes, each way, on the bus. I also use it to read. There's a library right next to my office! I'm going there this afternoon before I grab the bus. It's great.
When I was forced to work from home in 2020, the commute was actually one of the things I missed the most. You're correct that I could have just spent 40 minutes reading each day at home. But I didn't! I looked at my phone or cleaned the house or started work early or something. Having the forced structure is what works for me, to enforce different "parts" of my day. I catch the bus at 7 AM. I read for the 40 minute ride. I get to work around 8. I catch the bus home at 4 PM. I'm home around 5. It works for me.
Working from home didn't, I felt lost and bored and frustrated and actually had some breakdowns near the end of it and ended up going back to the office before I was vaccinated, which was kind of scary but better than waking up crying. I don't know why that's the way I am, but it is.
(Thanks for reading this comment. This is a reminder that this comment was from my point of view and was about me. You may feel differently than I do! That's OK.)
I don't see anyone in this thread doing otherwise.
This argument is absolutely insane to me. You weren't paid for your commuting time before - if work now fills that slot it's because you're choosing to work earlier/more.
