One of the consequences of a public transaction chain is the great potential for witch hunts. Here's one of the first examples, but it surely won't be the last.
That brings the frontrunners of Bitcoin in a predicament.
On the one hand they are often libertarians and very happy with the succes of Bitcoin. On the other hand, getting in early gives them some windfall gains, and law enforcement will go after them, since many of the real criminals using Bitcoin will remain elusive to them.
A little tidbit that will hit any of them sooner or later: did they properly file their taxes on the Bitcoins they mined? Trammell just admitted holding 800K$ worth of Bitcoins. Where did they come from? (Mining, I know, but those lawsuits will get hairy, because lack of knowledge.)
Well, no. He admitted to holding an amount of Bitcoins that would now be worth 800k. At the time he transferred them they were worth a 20th of that amount.
More people see that having financial privacy is a good thing, and trust in bitcoin grows.
This could also have a maybe unintended consequence of increasing equality, because some people, knowing who has the most bitcoins, might act to decrease the influence they feel is too large by, for example, choosing alternative product or service to use or buy. We see this effect already with people feeling that corporations like Google have grown too big and some go out of their way to not use their services.
