This is where the post-modernism I was talking about is at play.
Fun and the learning experience of getting good at something are not mutually-exclusive, and anything worth doing is worth doing as well as you can. Really, there's just no excuse not to if you're going to do this kind of stuff long-term.
There are many authors, sculptors, painters, composers, etc who were largely unknown in their time — sometimes they were overshadowed, sometimes they were more hobbyists — and died poor and the public did not come to appreciate their skill and works until sometimes centuries later.
This lack of reputation or even desire to be known in their time did not stop them from pursuing the highest levels of craftmanship they could. It's a lot more satisfying when even something you do for fun turns out really good.
Case in point: In Poland, some guys built an entire church out of salt just for something to do.
