I suggest to set the Inviolable property by default and make the
following simple modification to minibuffer-avoid-prompt:

(defun minibuffer-avoid-prompt (new old)
  "A point-motion hook for the minibuffer, that moves point out of the prompt."
  (if (= (point) (1- (minibuffer-prompt-end)))
      (constrain-to-field nil (point-max))))

This has the nice feature that backward-char does not move into the
prompt, but you can still `jump' into the prompt (e.g. using M-b) or
copy text from it using the mouse.
