Advanced security technology does nothing against the old attacks of "look over the person's shoulder while working in bed" and "your work is really interesting and important, please tell me more".
I don't know, maybe you're right. I, personally, am very uncomfortable (almost physically) if I know that someone is seeing my screen and I wouldn't be able to get any work done in such state. Maybe I'm just weird.

This one is unrelated to physically being inside someone's house.
Corporate security is a strong reason for leaving your work at work.
Never met a tech executive who left work at work. Also never met an IT security team who had the juice to tell the CEO what he could and couldn't do on his corporate phone...
