Why is it a crock of shit? If someone can get the work done at home quicker than they would in office then that should be rewarded. I could be wrong but isn't the whole goal of business to be efficient as possible especially if you are salary. It's funny because stories like what you said are often used but I would propose a counter story. I would say the least efficient ones are not the ones working from home but the people whose jobs are basically just being stuck on or creating meeting after meeting day in and day out.
There are countless people, mostly higher ups, who all they do is sit on meetings day in and day out. When something needs to get done you end up going to someone else to get said resource, or even better those people who hold meetings to go over the same things you have talked about over and over again.
