i think not every guitarist in the world play for an audience or on stage. its not very fair to say someone's not worthy of a guitar just because he plays a simple 3 chord song or that he collects it and keeps it in a humidity controlled room in its case forever. Granted instruments are made to be played, how they are played, who plays it and however it is used is up to the owner itself. point is don't judge. i've seen old uncles playing expensive guitars like PRS, Gibsons, Taylors, Suhrs, Andersons, Fender CustomShops. Can they play as well as (fill in the name of whoever)? definately not, but what fuels them is the passion, to just play for self-pleasure, as a hobbyist or to just have a pretty guitar hanging up the wall.
