If you're buying $30,000 of VGF, sure. Who cares about 500$.
This fee becomes really meaningful as these resorts age and the contract value itself gets closer to zero. Mathematically, this (and other closing costs) is enough to flip
DVC into worthless contracts as they age, like in other timeshare systems.
It's not about who can "afford" it. It's about Disney making money, sure, but it's also about paralyzing these contracts at end of life. It wouldn't surprise me to see it go up more just to restrict the transfers of 0$ contracts common in other systems. Disney wins when contracts are locked down and points aren't used or sold.
