It is what it is - it doesn't matter that you fail to see the goal of this particular loyalty program.
Like any other loyalty program, it extracts additional money from you beyond what you planned to spend. That's the goal of all loyalty programs. And
DVC does that in spades. But I guess you buy into the false theory that DVC saves one money.
And FWIW, there are currently 4 tiers in this program:
1) Blue Cardholders
2) Pre-2019 white card holders
3) Post-2018 L14 white card holders
4) RIV resale white card holders
