You're first sentence is not well supported by the rest of your comment. Why not keep a waitlist to gauge demand for immediate resale even if you have no interest in propping up resale prices?
You say
DVC's resale value is a good selling point. But have you actually ever heard of a guide mentioning resale value unprompted? Everything I have seen says that they really don't want to discuss resale at all.
A previous poster mentioned that DVC bailed out of ROFR almost completely during the Great Recession and you didn't mention that at all. An OKW contract supposedly sold for $25 - where was the floor then?
Riviera's restrictions should tell you that you are confusing correlation with causation. DVC's high prices correlate with active ROFR but ROFR isn't the cause of the high prices. Strong demand is at the root. When demand wanes, Disney's models spot it before most of us and they drop ROFR.
(And yes, there is a small affect - if I'm interested in Riviera at $100, I might offer $105 if I think I can avoid the hassle of ROFR. But if ROFR is set around $150, I'll drop out or look at Legacy 14 resorts instead.)
