I don't think this question can be so easily dismissed, Tateru. You're brushing right past this - is your real body "you" either? Is your hand "you"? Is your tongue "you"? You can point to any part of the body and realize that it is also just a tool.

The real question, and why avatar rights may become more and more important, is to what extent is this tool an essential part of your self-expression in the world. I think they will be really important into the next decade and beyond as a part of who we are. So, just like we have laws that assume that protection of the body is a part of "your" rights, it will be more and more important to people that their avatars can't just be canceled without some sort of legal recourse.
