Well I tried this as well, and tried out the new advice-add
functionality.

Here is what I tried 


(defun my-remove-all-text-properties-region ()
  (interactive) ;; that is not important
  (let ((inhibit-read-only t))
    (set-text-properties (region-beginning) (region-end) nil)))

Then 

(advice-add 'set-property :before #'my-remove-all-text-properties-region)

or 

(advice-add 'set-property :around #'my-remove-all-text-properties-region)

Result: no effect


I tried 

(advice-add 'copy-to-register :before  #'my-remove-all-text-properties-region)
or 
(advice-add 'copy-to-register :around  #'my-remove-all-text-properties-region)

Results in an  error:

At this point I give up
