Because this is a hobby, not work.
One of my longterm projects is to build a simple 68000 computer from scratch using real chips. By your logic that's a complete waste of time, since this has been done many times before. I don't care. In the end I'll have a small, very slow computer that nobody else has and which only runs programs I've written or adapted myself. Very irrational, but fun, interesting and very satisfying.
