The customize system is designed not to prevent loading even when libraries aren't found, e.g. settings persist after uninstalling their library, because it makes sense that if the user then chooses to reinstall they get to keep their settings. The counter option is that uninstalling a package removes that packages settings, forcing the user to go through and set them all again.

The separation of settings and source is a good thing, and ought not to trip Emacs over. The absence of the source should not matter a wink to the settings.
