A public ledger of transactions if augmented with more info about the transaction will certainly help to have a clearer understanding of where the economy goes. Instant statistics! probably an economist's wet dream.
The transparency of the blockchain will make it more difficult for Politicians to distort the reality. I think it is a great Idea (public ledger) on it's own.
I wouldn't easily discard that notion in searching for anonymity.
Using the example of a business owner, these are probably the most painful words I've ever had shoved in front of my eyes.

The next step is real business money. The only way to invite this, I see, is by allowing privacy from competition.
In a networked services oriented economy, getting your business transactions transparent, is IMHO an absolute must for free market to work optimally
Remember you can also see what all your competitors are doing also, are the gains not greater than the loses?.
But that doesn't mean you can easily identify who, all you may know is that he is a competitor if anonymity or pseudonymity is working.
