Mountain Ash is primarily used to protect humans from the supernatural. Scott became a True Alpha from strength of character alone, and it happened when he broke through Mountain Ash. IMO, it would have been awesome if Scott could walk through Mountain Ash ever since then, as it shows that him being a TRUE ALPHA is an exception to the rule, as his strength of character signifies to the supernatural properties of Mountain Ash that he is also a protector of both the natural AND supernatural.
