I said it before, and I'll say it again. People buy Glocks for the utility that they offer. That utility does not diminish with use. When you buy based on function instead of form, if the function is retained, the price will reflect it. If you buy form over function and the form is diminished with use or as tastes change, the price will soften to reflect that too.
I think this is exactly right. When you buy on object for its function, and it has the reputation of near zero degradation of function with use, then the value of that object does not decrease over time.
Why do old houses cost the same as new ones?
