It takes as given that the tech is here, and it's economically feasible, but it's not giving any arguments. Just blames the people.
It's also not exactly defining the problem space. Is it talking about air-air AC with heating? Those are common and very cheap. Is it talking about large HVAC systems that include hot water? Those are indeed a hellof a lot more expensive, but also a hellof a lot more complex. And no matter what the author is saying, technology isn't to the point of giving us hot water from heat pumps. The math just isn't mathing - to take cold water and heat it up to "hot" by cooling off freezing air, you'd simply have to cool huge amounts of air. Yeah, probably, if you put a room-sized HVAC system and spend a ton on electricity - but that's where it stops being competitive.
Is it talking about geothermal heat exchangers? Because those are indeed a lot more efficient - but also more expensive for obvious reasons. You need to drill.
