That's like asking (in 2006 after the Intel switch but before everyone heard of the iPhone), "If it's so much better, why doesn't anyone want a Mac?" Arguably, "the market" didn't even know what it was, much less why they should value one. It's not that no one wanted a Mac, it's that less than 1 in 25 did. If only 10 people went shopping, odds were none were looking at a Mac.

Folks like Lindal Cedar Homes spend money marketing livable homes as an experience, but the general population isn't yet aware of the benefits or why they should even desire such a home.
