Most of my pictures are prints, hanging on walls. But you need a portfolio to attract (paying) clients, so images have to exist!

So if I said I'm an ex-Debian developer who's released a pile of open-source software, for free? And does so regularly?
Seriously you're getting too personal there, and just wrong. Photography started as a hobby because I love people - in the same way that woodworking is a hobby because I like doing things with my hands that are "real".
But there are costs involved, I've probably spent close to 10,000 in camera-equipment, to have people steal your work, means that stuff doesn't pay for itself any more.
You mention proprietary software? How would you feel if you wrote open-source software and people abused the licenses? That's copyright infringement, and the same thing is a huge deal in the photography world.
Sure everybody has a camera, and fly-by-night people will take money for pictures. But that's like hiring a self-taught PHP-programmer instead of a kernel developer. There are skills, styles, niches, and similar involved that clearly differentiate photographers.
