I run a sole proprietorship. I've never incorporated because if anything happens to me, there's no one to back me up. If I had employees, I'd incorporate, just to make sure that someone had the legal authority to clean things up if something happened to me. (Of course there are other advantages to incorporation, but to me that's an important one.)
I see the corporation like a mechanism controlled by its owner just like one would drive a car. To confuse the corporation with the individual who owns it is like someone who thinks that the car is a living thing. Perhaps if you were a visitor from another planet and observed those pesky things running down those roads, you would think the cars were alive. However, for a educated person to make that sort of mistake makes me think he is flying so high on pot that he might just as well be from another planet.
Soylent Green is!
