But... why? The centralised database uses less power so it's a more efficient foundation. There are some situations where distribution might be worth that cost. A lot of those situations that people were excited about early on (a global currency / gold alternative) haven't proven to be robust to the overhead (although speculative investments and transactions you don't want tracked are working for some people)

All that said, how does a concert ticket ever fit into that foundation as a win... without bringing up a liberation type ideology?
