While I agree with your overall point, you seem to be taking a restrictive view on what people call/consider to be amateur. I normally am not very picky with definitions and appropriate derived meanings, but the different usages of amateur are in complete contrast to each other and frequently hinders communication. The typical reference of "amateur" X competing with "professional" X is not for the less skilled or less capable. It's from those that can, but choose not to derive their income from that activity. There are MANY people who have hobbies that they are profoundly amazing at but cannot do as a means of income. Whether it's not being able to do it on demand to not wanting to lose the joy of doing it because it's required, it does not signify a lack of discipline or capability. These are the amateur's people are talking about. Not just those that are wanting to do it but haven't found a way to "break in". For a good example, hit up any hole in the wall jazz club. You will see some of the most phenomenal performers get some pocket change every Friday night after working as who-knows-what to pay the bills doing something they completely enjoy but don't want to do full time for whatever reason.
