I don't mind Vintage and Rare, they offer a good service to a particular part of market. In the past I've thought of it like this: just because I drive a car doesn't mean i can afford or want a vintage Bentley, sure it would be nice but there's no way i can afford it. I apply this to the basses and guitars I buy.
EDIT:
As for selling your bass via shops I think you have to take into account one of the things you pay for is exposure, how many people walk into V&R knowing that there might be something special in there? I know I have in the past and will do again. It's like eBay, sure the fees are high, but your listing has the potential to be viewed by millions of people. Only shops like V&R have the ability to filter that down to those who can afford the asking price. That, im my opinion, is one of their main advantages and one of the things the shop takes a cut for.
