I think the main reason why Satoshi Nakamoto created bitcoin was for our individual freedom.
Our life has been made easy by the services offered by credit card companies, banks and other centralized financial institutions but everyone should know that these institutions have access to our financial assets which takes away our individual freedom.

Privacy is an important aspect of cryptocurrencies which can not be neglected. We don't want everyone to know how much money we have on our address and to whom we are sending that money and the most important thing is that we don't want governments to know about out holdings, that's where privacy comes into play. While bitcoin gives us enough freedom in that, we can say that it is still semi-private. There is still a lot to be done when it comes to bitcoin privacy but I am sure we will eventually get there.
