> The last part is only true because most of today's organizations and processes are organized this way. Objectively, there's very little (outside of the individuals ability/willingness to work) that can't be optimized for remote work using modern technology.

Only the most important one: communication.

Its like saying you dont need to meet someone in person before marrying them, because all you need to know can be asked on an email or a skype call..

> I've been working remote for many years now and even many large enterprises I have worked for recently have adopted tools needed for working remotely efficiently (easy video/chat/screen share, collaborative productivity tools etc.). At this point, my impression it's mostly mental barriers (managers!) that stall any progress in this area.

I have been mostly a remote worker and I'm positively confident in-office working is more productive than remote, the same way going to the gym is more effective than working out at your home for the whole. There are exceptions and deviations, but the generality is true. Thats my model, but reality also matches with that idea: othterwise remote companies would be eating in-office companies, but they arent.
