Well you've definitely got me out-cued in the cue buying department. I play with a couple of predators, and have no interest in looking into a collectible. (except possibly as an investment.)
Here's the golf analogy:

Now, these are obviously "high end" clubs. That being said, a $600 production line Callaway is still very much a "high end" club, even though it doesn't cost $75,000. It plays great, it's the club of choice for countless pro's, it has intrinsic properties that are objectively superior to other clubs, etc.
The fact is that whatever activity or sport we're talking about, you can pay what you want for an item. That would be true of frisbee, philately, wine, golf, etc... The market puts a price on things that reflect an aggregate of properties (including rarity, marketing, status, previous ownerships, etc...) that are unrelated to the intrinsic properties of said item, a premium is placed on these properties in order to purchase status. Which is fine, that is the way the world works.
The mistake is in saying that the Callaway isn't a high end club, because it's "only" $600 or $700, where as you CAN pay $75,000 for a custom Honma. Well, you "can" pay whatever you want for an item. The fact that some people want to pay $75,000 for a Honma doesn't mean that a $700 Callaway is not high end.
