I think that if someone has invested enough of their time, effort, and money into building a desirable brand/product/service, they deserve to reap the rewards. If a Knifemaker can earn a living selling his/her wares based on a customer lottery system, more power to 'em. If they open their books, have ten years worth of work reserved and customers that are
still willing to wait in the queue for 'their turn', so be it.
But I'm sure even the most in-demand Maker has customers who flake-out on their orders or disappear when their turn comes around. I can see there being spontaneous gaps in the Maker's production schedule. How would one fill these gaps and still be fair to their customers in waiting? A lottery perhaps? Who knows...
As to the knife-flippers, well, profiteers will always be around like seagulls on a wharf. Swoop and snatch. If you want what they have, you pay their price (or you don't) and move on.
I do have an issue with Makers who misrepresent the wait time to deliver. I once placed an order with a well-known Maker and was told 18 weeks for completion. I waited over 2 years with no response to my casual order status requests (which amounted to maybe 3-4 e-mails over the course,) so I sent a polite e-mail to let him know that I was no longer interested. That, too, went unacknowledged. If he had told me from the get-go that he was too busy to accept new orders, I may have considered future business. Sadly, that bridge is burned. I still marvel at his knives, though.
Just my 2¢...
