People are so tired of being governed from any government, they want freedom and the decentralized system is the best for them. Everyone wants to do it, because it is best to do business without a third person and no one knows and little fee.
Anonimity with decentralized currencies is questionable because of the simple fact that transactions are public. I don't think that is a real concern tho when comparing to fundamental benefits. Can you give examples of cases when anonimity is of real use?
