The insert profit center drives big sellers. Guys like Cardgary that buys 5000 boxes but now find themselves with a ton of inventory that isn't moving for prices they felt they should be getting based on previous series. If the big sellers quit buying then what do you think happens? It's pretty obvious.
If sellers can't move their ANS8 stuff and take a big loss then their orders will be quite a bit smaller for ANS9. If that happens ANS9 could be the last retail wacky series and to me that is a disaster.
I don't disagree with your conclusions, as you state them. I just think that, once you start designing a product around this kind of mass-buyer market to begin with, you go down a road that inevitably must end the line.
I say that because you can't sustain a product that routinely allows people to sell off bits and pieces and make their money back, the same month they buy it. Now, perhaps this artificial demand is the only thing that allows the product to exist in the first place - that's certainly up for debate, but if a product requires folks buying tons (so they can make their money on inserts), it's not a matter of if, it's a matter of when, the whole thing comes crashing down. At least in my opinion, and I'll certainly grant that there is room for debate, but I base that on my experience watching and studying these things.
It just reminds me of kids in a baseball card shop, in the early 90's; buying packs, opening them in the store, and selling singles back to the owner of the shop, somehow making their money back, and buying more - it didn't seem realistic, and of course, it wasn't. That kind of return isn't realistic, and causes unrealistic expectations of what the product will give you.. and that leads to overproduction to meet an overinflated demand. Which is bad. If you're designing a card set as a secondary buyer's profit center, I'm not sure what you're designing, but it no longer is an entertainment product.
It's why I was somewhat concerned when the Old School 2 print run was increased to 5,000 boxes. I thought that was risky, and possibly detrimental to the future of the series.
