Many people are using it not only anarchists. I hope many people around the world will be using it everyday
The initial users for Bitcoin were anarchists, libertarians and users interested in drug purchases or gambling over the internet. Since then it has expanded greatly to include a wider swath of the population, albeit still rather small compared to competing financial solutions.
Satoshi had privacy in mind when he created Bitcoin as he covered that in his original whitepaper. If there's one area where Bitcoin is flawed, it's that it falls short of being truly private and anonymous. Given the momentum BTC currently enjoys and the amount of inertia associated with making major protocol level changes for a multi billion dollar airplane in flight, it's rather unlikely that true privacy and anonymity will be adopted.
This is the reason that XMR/Monero is of interest, even in a paradigm with the winner taking most of the market. As a minimum, Bitcoin replaces gold as a superior store of value. XMR/Monero could replace the anonymity of Swiss numbered bank accounts.
