This policy is like paying Macy's anytime you wear a shirt that you bought from them.
Paying for a private show is not the same as(or even similar to) buying a shirt. Paying for a private show is more paying for a service not an item. For example getting a message, you pay each time you want the service, you don't pay for the first time and expect to receive that same message for free afterwords.
If you want a discount on your VOD's you can join fan clubs or become a VIP. Re-watching our VOD's are still cheaper than going pvt each time, so maybe its best to be glad we get access to our VOD's at all rather than to complain they aren't free.
