Your Club 33 link doesn't prove your point. Club 33 was launched as a place to wine and dine corporate sponsors (i.e. companies paying to advertise at Disney properties).

The only non-sponsors allowed in were those who paid for the individual memberships. Currently, those memberships get you "free" VIP access to the Disney park where you have a membership, but the membership fee is $25,000 and the annual dues start at $10,000. These prices don't include food or beverage.
