Must have touched a nerve to get such a heated response.
I don't have blinders on, and have not bought a SAM to run AmigaOS4.1 for just the reasons that you have written, but I am also not interested in any $50 PC's and doubt very much that you find complete 3GHz PC's at that price "all the time".
I have a couple dozen computers here (mostly Amigas) and one of them is a 3.0GHz Quad Core PC that I have had for a while and I would gladly trade it for a decent spec'd fairly recent (read Intel) desktop Mac, but I am very happy to use my 1.5GHz G4 MacMini with registered MorphOS2.4 running on it, and plan to use it more and more for everyday stuff and some AmigaOS/MorphOS programming.
I don't disagree with your assertion that the pricing of ANY Amiga hardware is high and not comparable to hardware for other platforms. I also do not agree with the OP's attempt at logic, but for the Amiga fanatics, price is not an obstacle. Most of them are just happy to have any hardware to run their OS of choice on.
Edit: FYI, AmigaOS4.x does not run on the Efika, only MorphOS2.x, and as I stated in my post, there have been a couple Efika's with the full registered MorphOS2.4 license included offered for sale recently for between $225 to $250.
2nd Edit: I also forgot to say that if MorphOS, or AmigaOS ever get ported to modern hardware, I will be second in line, right behind you to buy it. AROS is a great idea, but it has not impressed me yet.
