Luckily, every teacher I know is still being paid. Even those who are completely off and don't have to teach virtual classes.

Except they can work from home, and now that they’re actually required to their commute cost is way cheaper.

Some teachers CAN work from home (not PE, Home-Econ teachers, etc.), but it's a less-than-ideal situation.

Are children self-motivated enough to work from home? I know many adults who aren't. Without adults to keep children accountable a total work-from-home schooling is likely to create gaps in the kid's education. And which type of child is the least likely to have an adult around keeping them accountable? Impoverished children.

A counter argument is that keeping kids physically proximate often exposes them to violence which makes school a lot harder and tends to really mess people up.

Lots of modern jobs worth doing will end up remote (at least occasionally and often permanently) so it’s probably a good idea to start training them when they’re younger anyway.
