When you say identity validation, do you mean connecting real-world identities to Steem identities? Or just identifying individuals on the network to prevent abuse by bots?

and on vote-canceling, I thought rewards pool is paid out periodically, and once it does that transaction is recorded and made irreversible.

dispute resolution would require Steemit to adopted a constitution, and there will elected individuals, mostly likely from the pool of Witnesses that would have to make decisions that are not programmatic, moving out from the realm of computer-science into legal theory. Do you think Steem is ready for that?

I don't quite understand the last two points but I'm very interested in what you've named as bonded behavior; can you elaborate?
