As something of an anarchist myself, I get where you're coming from. I was (and still am) also a bit put off by Ripple's alignment with the banks. However, on a pragmatic level I think it's important to realize that the banks aren't going away, and neither is crypto. Ripple seems to be one of the few altcoins out there that fully realises this, and is working with banks rather than against them. Principles aside, it also seems very likely that Ripple's value will increase as it continues to do so, so it seems like a good investment from a purely financial perspective.

At the end of the day I think the more Ripple (or any coin) becomes more widely used and recognised, the better it will be for cryptocurrency in general. An ideal situation for Ripple might be one where banks use and promote it (thereby increasing visibility), but individuals can also take advantage of Ripple outside of the banking system. Seems like that would be of benefit to everyone.
