You're perfectly right but it's difficult to build any minimally complex
programmer without encountering the chicken and egg problem.

That's true but from a pratical point of view, for the moment, you can just choose a simple serial programmer with external power supply (if you're using an usb serial adapter) or as an alternative it's easy to find someone with a serial port or a friend that could program the pic for you. Or as a last resort ask someone to programm the first one for you and send it by mail.
So the problem is fisolofically interesting but it's a real problem in
the real world?
