Well, I certainly don't think that you can either accept all or none of the traditions at once, but I do think it's a bit odd that you expect a ring but wouldn't change your last name. I gotta hand it to Doctor Bagel - she's more consistent than I was initially expecting. I certainly don't view my wife's last name as a sign of my ownership of her, much like I have an illuminated spruce in my living room in December, even though I'm not celebrating Yule. It's just tradition.
If you find someone who's willing to go along with your plans, then I really don't care at all (and if someone has a professional reputation based on a name, then that's understandable as well, but you can use a fake name in some cases - Brad Pitt's ex-wife's legal name was Jennifer Pitt
). My wife and I have fairly traditional views of marriage and family. Both of our moms quit their jobs after having children and stayed home, while our dads worked. My wife intends to do the same, more or less, and that's something that I think is good as well.
