The only people I hear argue that, are Kickboxers and Eastern Martial Artists, many of which believe that their Chi/Ki will finish their opponents for them
Oddly enough, for you MMA fans, Judo didn't even have ground stuff (Ne Wasa) until the early 1900s when Dr. Kano
developed them and incorporated them into Judo. He even SAID they were only necessary for sporting reasons, after he took the combat elements out of Judo. While it was a Combat Art, Judo didn't have a NEED for Ne Wasa. So much for the combat BJJ.
The story in itself is hilarious. Dr. Kano's school was fighting another dojo, and the other people were frightened because Kano's was undefeated. So they came up with a TRICK! When the fights would start, the challengers would
fall on the ground. Since the rules said you couldn't stomp them to death (judo now being a sport and all) they had no idea what to do with them. To make a long story short (I know, too late) Kano's students wound up getting swept and losing the matches on the ground. After that defeat, Dr. Kano decided that since Judo was now a SPORT, he had to develop ground work. Which he did, after several years of work, and integrated it into Judo.
In an interesting parallel (for me anyway), concerning the inevitability of going to ground. In the old days, Cornish collar and elbow wrestlers would have matches that lasted ALL DAY, with rules specifying what happens if no one wins by sundown. The fights were to the first wrestler to win
5 throws against his opponent.
Maybe most people just don't train to stay on their feet anymore. There is not a reason too now days. But in fighting cultures, in their games you lost when you went down because if you did it for real in battle, you
DIED.
