I hadn't really thought of it this way (because I don't care) but on reflection it turns out that the vast bulk of my contribution to the world does not contribute one iota to the GDP (except perhaps through some very indirect measures). So much the worse, I say, for the GDP as a measurement tool. There are two problems with GDP. First, it does not measure the value of things that are free, even though society benefits greatly from them. Second, it does measure the value of things that are not free, even if they represent no form of production at all (for example, bank profits). It's not clear to me, additionally, that we should measure 'benefit to society' in terms of 'capital' at all. A peaceful moment is worth nothing, yet it is everything.
