The best things are made by people who make them for specific reasons, even if you don't agree with or understand those reasons. Good art is made by including aspects that you want and rejecting those you do not want. In the case of Hundred Rabbits, their entire body of work would not exist without these motivations.

And really, I doubt that many people make things "just for the heck of it". In reality, they probably have motivations but don't, won't, or can't articulate them.
