But I don't think anyone should need an excuse to write.
Maybe they shouldn't, ideally. But this isn't a perfect world and even people who want to write often need a little extra motivation or an excuse to tell their family or something. Desire doesn't make things easy.
Personally, I don't have any respect for anyone who decides what other writers "should" or "shouldn't" do to be writers. What other writers do or don't do isn't anyone else's business unless they're paying the writers bills or the writer is asking them directly.
