Mine doesn't: "Note: file is write protected"

I can't: "Buffer is read-only: #<buffer 1>".


I can if I do M-x toggle-read-only, but then when I go to save the
file I am prompted "File 1 is write-protected; try to save anyway?".
This all seems pretty robust.

Not really. It does what you tell it do, and provides you with plenty
of notification as it does so.

As described, your Emacs is not behaving in the standard way, so
something on your system must be making it act like this.
