Why?

  All sorts of reasons. KYC/AML: the exchange wants your business so is more willing to drop their standards. In most markets most participants trade through brokers who also need to do these checks. Market making: the exchange has an unprecedented insight into how it matches trades and the scope to front run other traders. Perhaps even introduce "oops" bugs that their MM then exploits.
