What an excellently worded comment and great analogy. I've witnessed so many similar things in Japan. It isn't until very recently that new houses in Japan were built with insulation. Why? Wearing a bunch of layers, slippers, sitting in front of a kerosene heater or under a kotatsu... It works, so why fix it? Maybe it's a lack of creativity, critical thinking, or suppliers.. but it doesn't matter. If it kinda works, don't fix it. Which is interesting, because hundred of "keep warm in your house" little junky products have come out in the past decade like USB warmers and whatnot. And yeah, there are some arguments (other than the status quo) against insulated houses: more cost, when houses are seen as a one-type-thing and not a long-term investment. No basements for a furnace for central heating. Earthquake standards. But really, it's mostly just the same "Why" from your comment.
