Hey there, thanks for commenting and thanks for taking the time to read the paper 

The consensus algorithm used to deploy Bitcoin (where we use mining) makes perfect sense for the first virtual currency.
However there are now more advanced methods which can be used to achieve consensus without diluting the value of each individual coin (for example DPOS).

I do comment on the fact that these metrics may not be hugely helpful for Bitcoin but would become helpful once we start looking at various virtual currencies or DACs.

For example we can use these metrics to compare Namecoin and .p2p (http://bitshares.org/industries/domains/) to help evaluate which is a better investment. Without these metrics how would one quantitatively decide which of the two is the better investment.

I have written a white paper on producing financial metrics for Bitcoin.
I drew on many of the ideas from Daniel and Stan Larimer's ideas on thinking about virtual currencies as being DACs. I then tried to use this concept to produce common financial metrics which analysts would normally want to work with.

It shows many of the unsustainable issues Bitcoin has. If the same metrics are used to analyse the DACs the Bitshares community produces we will see much healthier financial state of these DACs compared to Bitcoin.

I'm sure the community will be able to think about this in a more advanced manner than what I have put together, however I hope this paper is interested and helpful.
