As stated ronin played a key role in Japan's abrupt transition from a feudal society to industralism. I think this was a great thing. These warriors were able to think for them selves and act accordingly to their will. They were able to grow independently. Im sure their were some who liked the way they were living. As for if we live a ronin way, i think that is all our personal opinion, this is a free country and we are not forced to follow a certain predeterminded life for us. we are able to choose what path we take. there are all sorts of religions and lords that each indivual might have or follow.
As for the Maverick, being used to describe a ground for a ronin being a free and self directed individual sounds like a more sensable definition to follow. I choose to see that definition plainly meaning that you are free to make your own decisions and are self choosing for your life and the path that you lead.
