I read an article (can't find it now) that said from a previous project the Docker authors concluded they wanted a daemon so they didn't have to do things like file locks, etc. around image management.

Don't know if that accounts for the whole reason or not.

Sounds like it might've been this article?

Oh yeah, I read that - surrounding the original authors at dotCloud about their experiences trying to do it in multiple processes IIRC. That said, it seems the problem may be somewhat solved at this point.

The reason boiled down to "it's easier to write a daemon to handle it all". But it's definitely not better than the alternative, nor is the alternative impossible.
