As stated before, artists are willing to pay US$ 6000 and more for a single color print, but won't pay the same amount for Kodachrome's color palette. Offer that amount of money for a roll of Kodachrome developed to specs, commit to 100+ rolls per year (alone or with others), and labs will beat down your front door to do it for you even on weekends and holidays if needed.
I don't think this is at all accurate and is actually pretty typical of web-rhetoric. Firstly, you do not know every artist and many of the ones who actually have this kind of cash are not to be found on internet forums. Secondly, labs won't be beating down anyone's door regardless of price because it is next to impossible to recreate the same level of quality in re-making Kodachrome film and supplying the needed chemistry to the labs that are willing.
I was willing to pay another *person* $250 a roll to finish a small part of a bigger project on the film that did not gain enough traction before the processing ended...if you want a hint of what that was, watch the film "Tim's Vermeer"...I bet he got the idea from my pursuits and Hollywood inquires. And in a 5 year period, I paid several tens of thousands of dollars to use and process the film. I would pay top dollar to a real lab to soup my existing film if the chance ever arises. But I am not going to risk thousands of dollars on some experiment when it could go towards funding other projects or bodies of work that are a sure bet.
It's not that people will not put up the cash, it is that the film and the means to process it to be a piece of actual "Kodachrome" film are dead and gone.
It's unreal how not into actual picture making people are, it's better to just keep on beating the same dead horses of lost materials instead of producing mind blowing photographs that will help companies like Ilford, Kodak and even Fuji continue to sell great existing products.
Kodachrome film and processing as we knew it is *never* coming back, at any price.
