No. This may sound harsh, but some people refuse to accept reality. The Amiga platform is more than 1/4 century old, it is an antique hobby for collectors. Simple market forces are at work, supply and demand.
Don't get me wrong, I've seen some head scratchers. I've seen some fairly common items get sold on eBay for ridiculous prices, but those are usually one off events. Someone lists an item for an absurd price hoping to net a sucker. Usually they don't but occasionally they do. Overall, over time you will simply see supply and demand forces at work as they have since the beginning of time.
