Curious, what are some of those advantages, & do they seem to be worth $50/pp ?
Definitely, which is why the restrictions are baffling, to me they just hurt DVC value overall.
Not OP but for my wife and I, we bought direct at Riviera in January (200 pts). Two major reasons!
1. We are in our late-20s - so 2042 resorts getting removed in 19 years means a lot more to us than perhaps someone in their late 60s. It also means there is a good chance that there will be more than a few new resorts by the time we are done. Unrestricted points is a big big deal for that.
2. Discounts/Benefits - not really a deciding factor but in my opinion, its a nice to have. i think you would be hard-pressed to see all the discounts disappear and of course, you spend a TON to truly break even. But my wife and I are going to try a moonlight magic at HS and have already done one at Epcot this year. That is close to 800 in value.
You are paying for piece of mind that you aren't getting screwed out of something in the future. Not having to deal with the 60-90 day process of resale also has value.
