Tim Weiman,
You have stated before that increasing length of courses increases costs, but I wondered how much? Allow me to play devil's advocate for a second.....
Right now, a 7000 yard course typically sits on 180-200 acres. Let's use 190 acres. It costs from 3.5-5.5M to build, excluding those small percentage built by Fazio, et. al. or about 18-28K per acre. We'll use the low figure, since presumably greens and tees would be the same in either case, and they are the bulk of construction.
Raising the distance to 7700 yards (the longest course I see these days, so I won't use 8500 yards) requires about 14 more acres. (700 yards X 3 feet/yard X 300 feet wide corridor divided by 43,560 sf per acre).
If the cost of that land is $3000 per acre and construction cost is $18,000 per acre the total increase in cost is about $300K, shamelessy rounding for simplicity. If debt on a 20 year note is at $9/1000, using typical interest rates, it cost the owner about $2700 per year more to build the longer course.
If maintenance budgets go up 10% (again, high because the high maintenance greens and tees remain the same) from $600K to $660, the total annual cost is about 63K.
Amortized over a typical 32,000 rounds, this means $2 per round. If a golfer plays the average 25 rounds per year the NGF reports as typical, the cost is $50 per golfer annually.
In addition, I don't know of many architects who build courses much over 7000 from the tips, unless specifically instructed to do so, because of the possibility of a tournament. The one I designed at that length didn't really increase turf acreage at all. The way back tees had almost 200 yards of native between tee and fairway. Cart path went up, but that cost was nominal.
Looking at it that way, the cost issue doesn't really hold water. And, I'm not sure there should be a czar of golf, dictating just exactly what and what not technology SHOULD do, as we would likely lose many good innovations (unless you think the sand wedge, or even the lob wedge should also come under scrutiny by someone who is smarter than us....well, at least me
The increasing cost of our higher end golf courses is a product of an arms race all its own - the desire for better ammenities than the next guy - rather than the technology wars. Ultra long courses aren't being built in great numbers....and I foresee that they won't be, but that courses will probably be targeted at more specific golf audiences.
The issue is really more emotional for many, in that we don't want to see classic courses no longer used in competition by the best players. But that horse has already left the barn, in that the PGA Tour will only place its events on TPC courses, if possible, designed specifically for players of Tour caliber. The horse really left the barn when Prestwick was taken off the British Open Rota.
