Look ! His My PIN number is 8723 and here's a statement from the ATM I obtained earlier today using said number in the presence of a ~mark~~ witness.

No, my friends, it is neither a necessary or a sufficient proof of identity for someone to have a PIN number to a bank account. To Verify^TM an identity you need to consider a number of different and independent pieces of corroborating evidence.

This will be even more of a requirement where you either have suspicions, or indeed evidence, that said claimer is in any way dishonest or dodgy. For example being investigated by some authority.

With regard to Satoshi do we have any other evidence, apart from that presented during Gavin's personal Magic show, to corroborate Craig Wraights claim ?
