And, of course, not everyone can buy resale. There's just not enough supply. Disney moves 10 times the number of points each month than the resale market, because most current owners are happy with their ownership and don't sell. So resale is an incredible deal as long as most buyers don't know about it.
I actually think the best thing Disney could do to "fix" the resale competition would be to emphasize the resale market to every buyer, and go ahead and tell them where to go look at the resale market. They could emphasize that if they aren't happy with their
DVC purchase, they can sell it on the open market. For a short time, they'd lose some sales to resale, but pretty quickly resale prices would shoot up until they were just below direct, at which point people would see direct as an incredible deal. Having a vibrant and high-priced resale market is a huge benefit to a buyer, because it means they will be able to realize a good price when they sell.
