No, I have issues with how registries are used. They should not be used to hit people over the head with the recipients material demands for gifts. But rather to offer suggestions when asked for. Providing registry information should only be done at the givers request. It's really no different than verbally inviting someone to your home and then saying, "By the way, you'll be bringing the dessert, and we want that strawberry cheesecake from the bakery on 5th Ave. So just pick that up on your way."
Well the point of the registry IS to let your guests know exactly what you want and putting the little card in the invite is a convenient way to let them know, there are many who appreciate that. However it is up to the giver to decide to get something from it or use it as a guide. I think way too many people assume that registering for specific things is the same as demanding them and the recipient is some spoiled brat who will shun you and your gift if its not something they had on their list, but that happens less often than not.
What I get from your logic there should be no registry on paper but its okay to ask the bride or mom to be what they want. Which in my mind means you do have issues with a formal registry since its purpose is not to give suggestions but to give a wish list of specific items.
