Very good point. The best developer I ever worked with said to me one time "I'm thoroughly unemployable", meaning his skills, motivations and long term goals did not match what-so-ever with those of a employee developer.

He was a great resource but hiring him permanently would be a terrible mistake for all parties.

I've worked with some like that, they're easily bored and will work well as tech-cofounders, the ones who can rewrite the entire code stack in a weekend.
