"The Gates" cost $20MM - or did it?

Over at greg.org, there's an amusing and thought-provoking analysis of the much ballyhooed $20 million figure bandied about as the cost for "The Gates".

"Whatever the Christos' can convince their accountants--and the IRS--to accept, more power to'em. Given that they've set up their practice as a professional corporation whose core competency is persuading bureaucracies to allow them to do massive, nonsensical things, maybe their accounting practices are a conceptual--or absurdist--art work themselves."

Whoa, look out. Christo and Jean-Claude are rather adamant that their work is not conceptual art, which one would assume extends to their accounting practices. Plus I'm not sure that Greg has taken into account Christo's claim that he works 17-hour days, 7 days a week.
