Since RS controls the control nodes and the control nodes control the block chain and the block chain controls the currency, RS controls the currency. At a whim, he could undo transactions and lock wallet addresses out of the system.
He's already proven that.
You can "undo" transaction in EVERY cryptocurrency by overwriting a block by remining it, nothing new here.
But how would to lock out a wallet? No proof? That's your usual way, accusations and then post some excuse or "It has alreay been proven.", but no facts 
It is been made abundantly clear that you can neither read code, nor write it. So hush up while the adults talk.The simplest way to lock a given wallet out of the currency would be to have the control nodes overwrite every block with a transaction to or from that wallet address, thus preventing it from spending, receiving or mining. Those actions can be taken in piecemeal or in concert.
