Well, the term “outsider art” refers to people disconnected from the art scene, artistic education or art circuits. People that produce output that may be considered artistic but often for other reasons than to produce art, like channeling and manifesting mental or emotional turmoil or trauma. This is also why it is problematic to display works by “outside artists” in art contexts because they are not necessarily produced to be seen, analysed out judged by anybody.

So yes, “insider art” is really all art and crafts that work within a tradition, any sort of context, by people that are aware of their activities as artists, regardless they are professionals or hobbyists.

I’m not sure what you’re going for here or if it is just a playful game with words.
