If a responsible breeder de-registers a horse because it is not of breeding or show quality, and a responsible owner buys it and decides not to breed it for the sake of using all its organs, then the horse world would be much better off.
Unless there are health- or age-related reasons for not showing a horse, that responsible new owner who bought the horse and chooses not to breed the horse should be allowed to show the horse in at least
rookie or novice competition and/or introductory shows (I'm using the AQHA terminology for entry-level competition classes) if (s)he so wishes. The former owner wanting to avoid competition or being afraid of being shown up by a horse (s)he abandoned should not be a factor.
