I don't care about my own remains, but I think funerals (and memorial services, which is all I have attended thus far), are psychologically important for the closure they offer, whether one believes in an afterlife or not. For instance, the way many say it's worse to have a relative "disappear" than to have one turn up clearly dead; even if death is certain (such as Vietnam's MIAs), the survivors are left in an agonizing gray area with no punctuation at the end of the sentence. This isn't to say that there aren't people out there who wouldn't care one way or another if a friend/relative had a funeral, but I suspect they're very much in the minority.
