I look at it as being like a top end car (say a Ferrari). If you want one, typically you have to wait. It's part of the exclusivity of it, which doesn't mean it's a good thing, it just is what it is. It's up to the consumer, you can place something on order knowing that you may have a wait, or you can buy something else now. The choice is up to the individual who wants the item.
Personally, I am willing to wait for a set of AX-Lightness brake calipers, knowing it may be many months and in the meantime use something else knowing that my bike is awaiting some icing on the cake. But that's my choice as a consumer, just as it may be the opposite for someone else, neither is wrong, it's just their choice.
