I think that "old timers" have had the USE of
DVC accommodations over the last 5-15 years and seen their annual trips become multiple trips per year.
Some of these "old timers" are close to the end of their WDW trips years (kids grown, etc.) or at least have decided to scale back on their frequency of trips. So, if they were asked whether they would pay more money to buy into DVC now, they probably wouldn't be interested. Their current points are sufficient or too many. Also, the "new car smell" enthusiasm may have worn off.
We purchased in 1991 when my kids were infants and we could go anytime the airfare was cheap and DH could get off work. Now that they are both in grade school, we don't want to take them out of school for Disney, if we don't have to. Because, who are we kidding, it won't be a once in a lifetime trip, more like a semi-annual pilgrimage!
So, our trips are getting less frequent and during the more crowded, hotter, and higher points seasons! Not my favorite times of the year and not what I fell in love with WDW and DVC for. However, a day at Disney is better than a day at work and home.
We have more than enough points for our current usage right now even though we now have to travel at times requiring higher points. The first few years, we were burning up those points like crazy!! We purchased 3 contracts, 2 came with fully loaded banked points, and 1 came with 100 extra developer points.
So, SINCE we did go through the "honeymoon" phase of DVC already, if we had to buy now, the higher prices would bother me a bit and maybe cause me to purchase less points and be more careful of how we used them.
If my points disappeared and all the money spent went back into our bank account, I would still buy in DVC (still love it) but would buy much LESS points, because it wouldn't be as good a deal "to us anymore."
It's kind of like coming out of a restaurant, just finished eating a 5 course meal, and having someone ask us if we want to have the same meal but with even more variety but at a higher price. Since we are still full, some of us will pass. Whereas, a hungry patron walking down the street might jump at the chance!
