It seems my comp done fucked up again. Can you guys merge the posts? I meant to edit it and it made a new post

Well it's not like your regular riff raff actually trains in these things. What're the odds that the random pickpocket knows n̶i̶n̶j̶u̶t̶s̶u̶ muay thai or eskrima?

Its possible that it WILL happen eventually that a lot of guys who are riffraffs have some kind of training in it. Maybe not immediately, but soon.

I love Bjj due to the fact that it is as much a mental game as it is physical. There's this guy in my class who is a blue belt and he has quite a bit of weight to him. I mean beer belly chubby. But he just absolutely shreds everyone no matter how much bulk or endurance they have on them. Actually just getting to roll is good cardio already.

Well ultimately all combat systems comes down to the guy doing it. The whole concept of Mixed Martial Arts has shredded the myth that there is ONE style that is the end-all of fighting systems.

Quote from Jutsu

I never wore headgear or fought on a mat, instead I sparred out doors on the ground with only one rule "don't get mad."

I hope that works for you. I don't see that as being optimally smart or safe though. Why risk getting hurt during practice?
