Here's another:

I think Bitcoin is great accept for two things: its speed, and the infinite hashing power needed. Libertycoin eliminates these problems. Anonymity is great in a society based on solid moral footing. Or is it?  I don't know how solid our morality is these days. I think some serious study is needed to conclude anonymity to be, overall, beneficial or not. The only real way to figure out if it's good is to try it. Whether that will ever happen for money is anyone's guess.
However, remember to think big. To think big means an alternative to fiat currencies. A happy and cohesive society is not full of dark secrets. If the society is based on liberty, good moral ground, and natural law, why do we really need to hide our money movements. The largest benefit I see with anonymous money is to avoid the fraud and money controls set in place by the government. In a lawful society, these controls would not exist. I'm not firm yes or no to anonymity.
