There IS one aspect of this, however -
This is unquestionably the future. I agree that some jobs cannot be replaced with all remote work. I have been told that the IRS *mostly* operates with staff, from home - and that began many years BEFORE THE PANDEMIC.
Just as email and electronic messaging is erasing snail mail and such - the virtual office IS the way much commerce WILL be done. My sister has been working from home since the 2000's.
There are a lot of reasons - one is, as government staff increase, the need for more building space emerges - there's just only so many broom closets and hallways that people can work in, before you have to consider - do we build ANOTHER building - rent space, locally - or allow more people to work from home?
I know OUR productivity has not flagged, but for a few reasons - we track EVERYTHING. Every part of our project is broken down into tasks as short as one day - OR LESS, and as long as one week, and we track it regularly. Nobody gets away with doing nothing for days or weeks on end. You don't just show up and say, yep, done it. It gets tested, scrutinized, reviewed. If you say your stuff is done, someone ELSE is reading it within minutes. You simply cannot "cheat". You MUST be logged in, and logged into Teams and so forth and you get logged out if there's inaction more than a few minutes.
I don't find it onerous - but I would face the same system if I was physically present, except I would also have to lock up my workplace if I so much as visit the restroom. And it means I never see a co-worker even if I am IN THE OFFICE. My job doesn't change.
