An important job for direct line managers is also to let bad ideas die in a way that doesn't create chaos in an organization. That's hard to do with remote workers.
It's the reverse. By far, and by far I mean incomparably far, the worst ideas I ever saw originated and directed were in verbal meetings where no one was going to say no to an incompetent and petty boss. I saw millions of dollars and thousands of man-hours get wasted away. I watched staff of entire departments leave for other companies, often competitors, because they knew it was going to fail spectacularly. I witnessed entire companies go under because no one was going to put the brakes on such bad ideas.
Now, if it can't stand scrutiny from being put on paper (digital of course) and reviewed across various teams, it doesn't get started at all. It's amazing, and relieving, to witness the increased level of accountability.
