So you mean BTC is mainly adopted by people wants 100% privacy? On the contrary, it's possible that the majority haven't adopt BTC just because of the anonymity. Most of people heard of BTC but haven't convinced to use them because they think the government will not allow such things to exist. The main objective of BTC foundation is not to increase its anonymity, but to explain to the authority that it's not as anonymous as they think.
This isn't about anonymity.
If the government wants to know who you are, they'll subpoena your landlord to tell them.
Are you saying the majority of people want the unknown to-be-rapist down the street to know their every purchase, telling him where you've been and what you buy?
They want the pedophile-to-be to know when and where they drop their children off at childcare?
