PBOC doesn't need to stop people from being able to move BTC funds around on the blockchain in a timely / efficient manner-- The miners have done that all by themselves! Also to address your "rightful owners" claim-- the rightful owner of a bitcoin is the person or company who holds and secures the private key to the wallet that coin is stored in. If you don't have that private key secured you don't own bitcoin, you own some type of bitcoin derivative backed by an exchange.
