Also painting/drawing, writing music or books, writing software/apps, blogging, cooking, racing cars, taking photos, traveling and writing guides, and having sex. All activities that people derive pleasure from that others happily pay them to help them continue to derive pleasure from it.
Cool, I want to race cars (not really, but anyway)! Where's my race car? Where's my piano to learn? My camera? My travel costs?
You aren't really going to give me any of those for free, are you... Furs are so cruel to their feathered friends!
Most people who do these things, aside from possibly writing software, don't get a cent for it. Even the 1% of them who do get paid for it have invested heavily beforehand in it with...the accumulation of resources, whether theirs or their parents'.
