How are the prices a problem? If a person is just looking for a picture not a particular artist or philosophical theories, AI is cheaper. If a person wants to commission an artist, that was always a semi luxury even for cheapest of cheap rate online artists.

In fact if your old price was already 500 dollars then its already a useless luxury. People think a lot before paying 500 even for actual tools, anyone who has 500 to spend on a non-essential luxury is already doing something most people don't have any need to.
