I think there are a lot of very tall people who would elect for surgery to make them shorter as that's a bigger issue. The world was made for people in Scott's height range up to 6'3 or so with little adjustments necessary. 6'4 and 6'5 are pushing it where you may have issues fitting in certain cars or certain rides may be off limit. But I imagine any guy whose simply over 6'6 with nothing to show for their height other than being tall and clumsy would gladly undergo surgery to get down to 6'4 or lower. Then there will be no issues finding trousers that fit or getting into small cars or entering rooms made for average sized people.
