Of course, no one can stop you from claiming anything, I could claim to hold the Juubi and no one could really do much about it.
You have simply been warned in regards to the standing point of two fairly relevant characters and the masses as well.
I am where I am today thanks to my efforts and what not, however, the main factor was the vast acknowledgement of the many, so I am simply going with what might seem like false cliche "By the people, for the people." Both sides have decent arguments which most here are well aware from various sources and events, and as such, what we'll be going with is the side with the many. I can find 30 people to agree with us in 10 minutes. Can you find half that many?
As for edo-tensei, as I've kindly stated, w/o a decent leveling down, it's pretty much god modish. It's not like Pete and Kamui did it cause they felt like weakening themselves for the heck of it.
Edit: Fyi, the first leveling down made by Pete was brought to our knowledge by him when the bijuu council or rather that attempt at one was strongly debating on banning it from bijuu fights, only bijuu fights due to the sheer fact that it is the only thing it governs.
