I completely understand your point of view and I think working from home is not for everyone. But many people do have the ability to delineate without that geographical reinforcement. I think the title of the post should be: "Employer Let Your Employees Work From Home If They Prefer" since its not a zero sum proposal.

This issues also exists though when a company has two offices that everyone is required to work from, one in London and one in SF for example. Relying on chat and informal lunch meetings is equally problematic for work form home as it is for employees of different offices. It seems like solving the communication issue for one solves it for both and companies seem to have no issues with having multiple offices.

I completely agree with you about email, I feel like we are losing the will to compose proper arguments and counter points or parse them in the context of email.
