It's not about proving they don't work. No one cares if you can't do that. But it's getting a bit embarrassing that every time we try to prove the positive, all the benefits disappear in the closer analysis. It's also not about the individual experience — again, no one cares. It was all about the benefit to the community. That's why your technical objection doesn't matter either — if the community includes a bunch of old codgers that can refuse to participate, then, regrettably, that's just how it is.
