Just a guess on my part, but with the capability of modern materials and manufacturing techniques chains could be made to last much longer, but it would cost a whole lot more and there just isn't enough of a market for that to make it worthwhile. If I were going through 20-30 chains a year, it might matter, but the number of people doing that is minute and most of them have sponsorship of some kind.
