If you want to start something, and nobody is interested in your idea or you can't find anyone good enough - Just start it alone.

If you have an idea, and you know a fellow co-founder that's interested in starting up - Just start it with him and work together.

Bottom line: Instead of thinking about the non-essential stuff- Just get the first prototype up even if it might mean doing it yourself.

Any school of thoughts that places restrictions on an ideal founding team size is crap. The debate that advocates an optimum team size is no different from saying that man cannot complete a mile in under 4 minutes.

Work with what you have, not what you don't have.

Exactly. And be aware of the risks. As a solo founder you need people you can bounce ideas off of. (And in my opinion this is the purpose of an advisory board, or even friends who have no skin in the game)... and as a group of co-founders you have the serious risk of conflict among the group.
