I share your frustration. However, it makes sense, if you think about it. Having to give a note a title makes you think it through, and with Zettelkasten you can easily split it into many atomic notes, each covering their own thing.
As a workaround, you can have one note dedicated to all your random notes, which you can periodically review and reorganize.
