I didn’t say that. Anything is better than nothing, but there is no way to know what type of situations can unfold in public. Let’s be clear, some streets are far and away more dangerous than others. If you haven’t spent time there, you may not even recognize certain dangers for what they are. Your chances of being robbed at gun point are far lower in Australia than in Southern California, New York, Chicago, Baltimore, etc etc. Being prepared for that has more to do with understanding cultural cues than martial arts. You may fancy yourself the toughest martial artist in the place, but it won’t matter a lick when some 14 year old is pointing a pistol at you. That situation just won’t happen in a ring, and it’s not comparable in my mind, having personally been in both situations multiple times. Have you been shot at? Robbed and beaten by multiple people at the same time? Robbed while being attacked by dogs? It may change your perspective about how prepared you imagine you are.
