"Securing" a PDF document with certain permissions implies that it can
only be read by later versions of readers (I can't remember which
versions started with the capability).  In this case, it still allows
you to save the file, open, or print it -- it just won't allow
modification of the file.

I don't use permissions, but I respect the intention of those who do.
Note that PDF passwords/permissions are quite easy to break anyway.
