He may be an asshole, but not for this. He's saying that even though he spent $166 million on it, it's not going to sell for that much so it should be valued at the $64 million it could sell for.
I don't know how this value is judged, but it sounds like a reasonable statement.
Put another way:
Just because I can spend $5,000 fixing my 93 Geo Metro after a collision doesn't mean someone is going to pay $5,000 for it.
