So this is such a good example of why the office is actually a major liability. Being in person allows you to get away with creating a culture where documentation doesn't really exist and that tapping people on the shoulder is more efficient. Everyone will be better off if instead knowledge is shared efficiently.

A good analogue is the culture of "the smoke break"(see the Friend's episode The One Where Rachel Smokes for a funny example). It's easy to say "the best decisions are made during smoke breaks therefore smoking is necessary for efficient businesses." Clearly that's absurd. It's not the smoking that makes good decisions, nor does the ability to tap people on the shoulder make for good documentation. Depending upon an accidental formation of office culture is never going to go well in the long run.
