So wait, your complaint is that the flying space station full of people in space is only providing data about people in space? That's not a useful criterion for judging its contribution the advancement of science, that's a personal judgement of the value of space-related research as compared to other field. And besides, the ISS is providing medical data on the longterm impacts of the freefall environment it would be literally impossible to obtain in another way. Whether that data is useful in another context is irrelevant. There's also plenty of crystal stuff (and I think some combustion experiments, I haven't really been keeping that much track) that rely on freefall that can be done conveniently in the ISS, and that recent growing lettuce in freefall experiment they did recently (again, primarily important for advancing work on human presence in outer space, but that doesn't make it any less of a contribution to science for being in that field).
Incidentally, if you want to talk time to operational status, ITER's almost certainly going to take longer to get running, and I wouldn't be surprised if it overran even that estimation. Just because something takes a while to be built has no bearing on how useful it is, especially if it involves difficult engineering problems, which is certainly true for a persistent human habitat in orbit.
