You still need to retain copyright notices with the BSD license. I think there once was a case where some BSD licensed code was copied into linux and the BSD license was broken.
A better analogy would be public domain. There's nothing really wrong with setting your code public domain (e.g. through CC zero). You're setting your code free for everyone to use without any conditions. If someone wants to contribute, they will, if not they won't. No license is going to change that. And the code in the version you put up will always remain in public domain.
