Having just started working again after a long run out-of-a-job (and an even longer run outside of the office), I couldn't tell you, either. My job so far only requires a handful of tasks that can't be done remotely (and that, frankly, could be replaced with access to a print center and a courier). Still, I'm required to make a commute that's minimum one hour, and approaches two for the method I can afford. My bosses have also taken offense at my "lateness" (8-8:30 arrival time, instead of 8 on the dot or earlier; sorry, the 6:45 bus hits traffic). Lots of downtime. Few complaints about my actual performance.

This job could be fully remote. I'm actually trying not to puzzle over the reasons it's not, because that would just make me more frustrated. But, gun-to-my-head: it's inertia. People heavily invested - sometimes literally, often overleveraged - in the status quo, and not especially inclined to be open-minded or rational about changing it. You saw that it took a global crisis where employers were suddenly caught on their back foot in order for remote to gain any sort of real foothold (same for rethinking transit policy, etc.). And then they've spent the following years trying to claw everything back. Incumbency is a helluva drug (and the withdrawal is killer).
