Never underestimate the concept of resale value. Some people do buy instruments and gear with the idea that they want something that will keep up a sizeable part of what they paid for. Or just simply as an investment. These with Gibson that seems to be their biggest gimmick.
Is it weird? Sure, but it is as it is. You get a lesser brand that is just as good, or your own custom build guitar, even by the best of luthiers, and chances are when you sell them you will get only a fraction of what you would have gotten when you had orginally bought an expensive Fender or a Gibson.
