So the first time on this forum I propose carrying a little more weight and everyone freaks out?

Seriously. I understand that in a best case scenario, a lock shouldn't really factor. But it's kind of a given that you might end up in a situation where you really need a lock.

And again, I'm really confused here. Whenever "lightweight" touring pops up, it's usually a countdown before someone mentions that on a bike, the weight doesn't matter much compared to, say, backpacking. So people lug around too many clothes and tents 2-3 times heavier than necessary, all the while claiming it doesn't make that much difference. And I suggest a simple bit of security for a pretty small weight penalty that can make the difference between having a bike and being stranded hundreds of miles from home without any transportation or gear, and folks react as if I've just suggested a 10 pound chain.
