That is a fair question.
By going with a frame lock, you are always going to have to carry its weight, which in my case is about 730grams I believe.
Sometimes when I am just going to do an exercise ride, I leave my chain and U-Lock off my bike, but I still have to carry that 730grams of frame lock weight, not that I see it as a terrible imposition.
If I tried to use a "normal lock" and chain, I'm not sure how much the "normal lock" would weigh and the chain on my bike is a Loop chain and I am not sure I have seen a separate Loop chain that is as light as mine, as it is a 6mm square link chain.
Yes I have seen heavier and more secure Loop chains around, but the main benefit of my sized chain(besides lowish weight) is that I can fit it under my saddle and around the saddle rails to secure my saddle, if need be.
