People at the X-games don't fall in ways that impart more force into their body than a slam or throw onto concrete imparts, especially when dumped straight into the ground without protective gear. And even then, the X-games has some of the highest injury rates of all athletic competitions.
I've already linked to video evidence of what a slam on concrete or even just dirt does to a person. People sometimes just trip on the street and break wrists and fracture other parts of the body. The MMA canvas is significantly lower on the GMax scale than concrete sidewalk, multiple times lower. And even then, you can sometimes knock a dude out by throwing him on the mat. I've literally never seen a video or anything of a guy being thrown to concrete and just continuing to fight.
This is a research paper doing on the topic for cheerleader safety. They outline the GMax scores for mats vs concrete and the difference is like 15x or more force imparted on the person. Dry dirt is about 3x-5x as powerful as mats

And you have to remember, this is just falls, not slams and proper Judo throws. Just FALLING from half a foot onto your head onto concrete gives you a concussion. Being THROWN with an osoto or suplex onto it could kill you.
I live in an upper middle class area of a large city and I still see bar fights happen. Duels used to be a thing of the upper class gentlemen. I don't think it's about economic conditions. And even so, if that's where real fights happen, than that's what should be simulated in MMA.
I dont have bloodlust. I don't want to hurt anyone (nor could I, I'm only a green belt and I weigh 150lbs lol). I just think if MMA is supposed to be THE martial art that represents "real fighting", it's not quite there yet. It's very close, but it's not there yet. Combat Sambo gets closest out of all styles I've seen, but even it artificially stunts throws and slams. Fighters will approach a fight very differently if they think being thrown to the ground will result in a TKO, just like they'd fight differently if they were fighting on concrete instead of soft mats. In real life you don't fight on soft mats.
TBH I think you should be happy from what I'm saying. You're a black belt in THE most effective single martial art on the planet.
