There is no problem in making a PDF such as this, however the edit protection can be removed easily. Once you make it harder to remove the protection you risk losing viewer compatibility. Even casual users can download tools with easy to follow UI's that remove the current Adobe protection, and can thereby remove the offending owner information.

Thinking of it a little more I realized that you can of course make it a pain to remove this user info, by placing the info multiple times in the file, in somewhat random formats that make it harder for tools to automatically remove the information.
