I think you’ve nailed the issue here. Sometimes folks fall into the mode of thinking there is one single correct way to go about training. There isn’t. Many ways will work very well. You get out of it what you put into it. You work with the methods that speak to you and that you relate to and enjoy. No single method is the best for everyone.I do not disagree with what you have said. A heavy bag will develop all those things at the same time. Makiwara training toughens the hands and the mind to some extent. There takes a certain amount of discipline or crazy (call it what you will) to repeated hit a board with the sole purpose of perfecting that one movement. I expect that after spending all that time dedicated to harding your hands and repeatedly practicing that punch you will become very good at it and have the hands to prove it.
It's a different mindset that appeal to some. People that that use it in their training or do other iron body work seem to think so but I expect that it wouldn't appeal to 99% of the people doing martial arts and that is ok too.
Incidentally, I train the heavy bag much as you describe the makiwara. I drill one technique at a time, over and over. I don’t “box” with the heavy bag. I’ve had some boxing/kickboxing folks on other forums express their dismay at that approach as well. It doesn’t matter. I didn’t try to tell them they had to do it my way. I just said that is how I do it. Some people get pretty bent out of shape over stuff. Shrug emoji.
