LenBum has the right answer. It doesn't, for two simple reasons.
Firstly, golf is challenging and fun in wind speeds all the way up to that situation mentioned by Steve and paul, i.e. ball being blown off green, but this latter sort of situation is extremely rare, even at the potentially windiest of golf courses, because, secondly.......
.........courses are never built, nor do all but the most foolhardy people live in areas which have consistent 3+ club winds (e.g. Mount Washington, the Antartctic). So, your point is really moot, and in fact I would argue, thirdly.....
.....that courses which do NOT have significant wind have an inherent design liability. I think occasional high (but playable)winds are good, consistently mild (1-2 club length) winds are most consistent with the principles and skills requried for golf, and courses on which wind is not a significant factor (through location or design--i.e. high trees) are lacking one of the essentials for a complete golfing experience.
PS--I've played a few competitions this year in 3-5 club winds, the last one this Saturday. This is a rarity, even in Scotland, and while I would not want such winds to be a steady diet, it was very much "golf" we played, and the skills required by all levels of players was significantly and pleasingly intensified.
