Even 1 day a week in the office is useless. It means you HAVE to live near the office or in the same state even. It's either remote or it's not.
And the days in office can be with your team.
I don't understand how allowing some remote work makes it 100% useless.
Video chat (for screensharing) with colleagues? Wonderfully effective. 64 people in the one Teams meeting? 100% seems to be "manager who can't bring himself to write a more then a 1 paragraph email and instead thinks too highly of his oratory skills".
Which has led me to my grand hypothesis that if you're calling a meeting just to give a fixed speech, write it out first and then decide why it's not an email...or decide just not to send it at all. If you think you need a meeting, then prepare the topics for discussion ahead of time and solicit an initial round of feedback.
Just decide that you meet e.g on monday, so you can plan everything
and spend rest of the week actually doing the work without disruptions
