That's very dismissive of the art and self-expression that goes into this. It's a strange, but pervasive human behavior, to make things not only practical, but beautiful. To put in different ideas into easthetics of things, to express yourself through them.

Of course, may be most shoppers simply go after current trends, but that's just true for any art form, from music to movies to books; almost all of these things are just as impractical. Investing your resources into something just because it looks nice is a very human thing to do.
