What I'm pointing out is the mistake people make extrapolating from very few data points about the space of possibilities now and in the near future in a long tail of possibilities for 3D printing. Per your example, It may very well be that nothing in the long tail of things to make with a 3D printer will appeal to you right now, and not for a long time. You may very well be a late adopter. But that doesn't mean that the entire space is useless, and of all the possibilities of things to 3D print, none of them will be useful or appealing to you personally. However, it will SEEM that way to you, since, by nature of a long tail, only a sliver of it appeals to you. Until that sliver gets discovered, by yourself or someone with more imagination, it's easy to jump to the conclusion that nothing will be appealing, given the samples you've seen so far.
