Good point.

It took me a while to understand why a lot of self-defence-focussed jiu-jitsu reminded me of Aikido so much, instead of more “efficient” styles.

But it makes sense for the intended purpose: you don’t want to immediately punch someone into the next time zone for being loud and pushy at the bar, or for touching you in a way they see as bold and you see as creepy. But a twisted joint communicates “do this again and it hurts more” pretty well, yet doesn’t do long-term harm or cross the line into excessive violence
