...I have to admit those Vero points are looking extremely attractive at what I can get as a resale.
Be mindful of the Vero dues. Due to higher insurance premiums and other related costs, they are $2 per point higher than most others. Over 29 years of ownership, you're likely to pay much more than an owner of a higher priced resort like Saratoga Springs or Old Key West which has lower dues.
As for the discussion of new construction vs. ROFR, it's purely a numbers game.
As previously stated, DVC can build new for $20-25 per point. That includes ALL costs associated with the development--design, materials, physical construction, outfitting the rooms, etc. If they can build new for $25 and sell for $165, why in the world would they ever actively ROFR at $60 and re-sell for $130??? You don't jump over $140 to pick up $70.
Aggressive ROFR also puts them in the business of trying to actively market a dozen individual resorts rather than focusing efforts on just 2 or 3 (currently Animal Kingdom and Aulani.) Much more expensive.
DVC only recaptures 3K-4K points per month at older, "sold out" locations. With such limited supply, they can set prices pretty much anywhere and buyers will materialize. With smallish contracts (under 50 points) being virtually impossible to come by on the resale market, owners wishing to add points in small quantities really have no choice but to go through DVC.
And don't ever forget about the uneducated consumer. According to numbers I've gleaned from multiple Disney webmasters, less than 10% of all DVC members are actively involved in any sort of online community. There are hundreds-of-thousands of current owners--and millions of non-owners--who have no knowledge of the resale purchase process. And many who do know about resale concoct their own justification for buying direct.
The timeshare industry only survives by the graces of the uneducated. Most timeshares can be purchased for pennies--not pennies on the dollar....literally PENNIES--via ebay, but developers continue to build and successfully sell at five-figure prices.
