Obscene pricepoints create a particular value. This is often marketed as "exclusive", which is in fact a suprisingly frank description: the value of an item to you is determined by the fact that you can afford it while others cannot.
It's like this thing in which people eat gold-plated steak. That's not because gold plating enhances the flavor intrinsically. The placebo effect certainly will have its effect, but first and foremost it's the primates way of showing status in the colony. If you demonstrate you can piss away extravagant amounts, your status rises.
€80K watches, €30K bags etc. have the same purpose. In no sense is a €80K watch necessarily superior to a €10K one (or a €1K one, or a €200 one), so it serves another purposes. So does ordering food in expensive restaurants, and then not touching it. And so are many things.
Marketing shindigs are such. Product price has absolutely nothing to do with production cost or product quality. Pricing is established to match a demographic. If BTY (or another brand) would produce a €10K blade and €5K rubbers we'd see footage of Justin Bieber, Paris Hilton, or some or other Trump, Kardashian, bin Salman, Lisin or somesuch using it.
Gold plated steak tastes great, by the way. Even better with ground dinosaur fossil tea.
