Mostly Harmless
For sure, there is a human element. I alluded to this in the analogy of the guy who lost over 200 lbs.And there are a great many who do use kata.
That was my point.
Now, I have to be a bit balanced here...
If an art exclusively practices kata and never does anything remotely like sparring I can see that it wouldn't be much use in a live situation. Say me doing tkd - if I only did patterns with no work on conditioning or sparring it simply wouldn't work.
Likewise, an art could ignore kata completely, say just do mitts and pads and running about. Like taebo. Is that any better?
From previous comments, it must be because there's no kata - but I have to disagree and say it's equal.
Now go to an art that ignores kata and only does live work - I can see that's probably quicker to fight than another art that balances kata and live work.
But, it'd be very unlikely to grab my interest. I'm not in it to fight, so it wouldn't fit me.
I contend it's much faster for me to reach any effectiveness with my doing patterns (kata) mixed with other conditioning and live work, because I do it.
100% live work? I probably wouldn't turn up, so guess what?
It'll never work
Look at it like this. from an efficiency or practical standpoint, the metric is about gains. I can build a chair with hand tools or with power tools. At the end, the chair is identical, but created in a fraction of the time using power tools. So, the argument in favor of hand tools is that there is value in the process. And this might be true. But in the end, you can't argue in favor of either process if, at the end, you don't have a chair. You can't say, "it's about the art of using hand tools...," and never produce a usable piece of furniture.
