Every bill has a serial number. Social graph exploration of paper currency is possible with bill readers at only a few points in the bill life cycle.

If the same nodes repeatedly 'touch' the same serial numbers you can infer a relation.

You make it sound easier and more powerful than it really is though. For all intents and purposes, cash is mostly anonymous. Bitcoin, on the other hand, is traceable if you can map accounts to real people.
