No. Espionage is rampant. Also, even a relatively good natured person might surrender to curiosity and gossip. Lastly and most importantly, other people moving in and out of the office is a security problem. Everyone assumes that anyone in the office is a guest of someone else or there with permission so you have NO security at all. DON'T DO IT.
A better option is to get a second monitor (or better yet a second computer) and find a "work buddy" or two. You can keep an active videoconferencing session going. Make an agreement to nag each other if one of you decides to take a nap, play video games, have a hooker over, not take is cocaine on schedule, etc. This will improve your productivity, and if someone busts into your office or tries to hypnotise you, your work buddy might call the cops on them. Or, maybe he will just sit and laugh at your bad luck depending on how much of a buddy he is.
A good reason to co-work is to bait people into trying to hack your computer while you leave it unattended. Then you can sue or just drag them off to your basement - whatever.
