I have a hard time believing that someone who decides to buy an electric bass and learn how to play it does so with the intention of only playing covers.
I can imagine people who want to play the violin, cello, even the piano, with no desire to make their own music, but electric bass guitar? I doubt it. (Please correct me if I'm wrong.)
There are a lot of guys on talkbass who only play covers and don't seem to have any interest whatsoever in making their own music. A lot of guys also seem to enter every discussion, whether it's about amps, strings, or basses, with the assumption that the intended use is to play covers.
So my question to you 'cover guys' is, what happened? At what point and why did you give up on making your own music?
You mean someone like Will Lee?
