Artisanal products are so expensive because we make them so.
By default if you buy something in a store, add 5% to the value by improving it and want to sell it on eBay, they'll charge sales tax on the full sale price even though you already paid sales tax on 95% of that. To avoid the double taxation you have to file paperwork, which most people don't know how to do, and pay filing fees, which eat into your already-meager profits.
If you want to sell things over the internet yourself, or accept digital payments in person, how do you avoid paying a fraction of the sale price that may exceed your margin to some payment intermediary that may capriciously choose to cut you off at any time with no recourse?
If you want to incorporate, your annual fee is the same one paid by Apple, but e.g. $500 is a lot more to you than it is to them.
Keep adding things like that up and individual-scale operations are no longer viable without charging thick margins and thereby having only the affluent as customers, which is what happened.
