Just reread your post. You literally said that what we have now is perfect. I don't know how this counterargument could get any easier. What we have now is obviously not perfect if people complain about it. I don't see what gives you the insight to say that it's perfect. Anyways, again, change couldn't hurt if it can be reversed. I don't see any harm in making it an "opt-able" gamerule. Trying it out would be interesting. Change is good.
That is not what violence perfected means at all. They are not perfect fighters... their limbs break off.... why not their grabs? It's just a catchy phrase to support the game. It doesn't mean that tori and uke are perfect fighters. No idea where you got that from.
Like I said, assuming things are fine as they are without testing something that a lot of people think would make the game funner just promotes stagnation. Why would you want that? Why not just try it?
