That's absolute complete and utter nonsense.
I've had AROS running on systems from amd k62's, to pentium3s, athlonxp's, athlon64, athlon64x2, Intel atoms, Intel core2duo, and phenom2, Intel i5s, and now Intel i7.
The i5 system cost me $100aud.
Additionally the hilarious justification that "the original amigas cost just as much new" is nothing more than delusional self justification. Back then ram was very expensive, so were hard drives, so were monitors, etc, etc.
The pricing benchmark has changed. These days you can pick up a machine 10x as powerful as an x5000 for 1/10th of the price.
Nice bit of creative writing there, but seriously why bother? Both you and others know its mostly crap. Never understood why people make up things when they must know others know the truth.
Is it self justification?
