I think you are misunderstanding Disney's Right of First Refusal.
Disney doesn't "disapprove" a sale....it steps in and replaces the buyer if the price is "too low".
Disney does this for two reasons that I can think of.
1. Helps prop up the sale of new
DVC contracts by keeping the selling price on the resale market higher than it normally would be. Without Disney's ROFR policy, resales would be much less expensive than new contracts through Disney, and they'd no doubt have a much harder time selling new construction.
2. If the price is low enough, Disney can turn around and sell them at their rate. Thus they can make a profit on the resale of points that they buy at "bargain" rates.
I think you are thinking that Disney just kills the sale altogether? No, they just take the place of the buyer, and it is the prospective buyer who is out of luck.
Let us know if your question is different from what I think it is.
By the way, I see this is your first post. Welcome to the DIS boards!!
