I just encountered the statistic that every year 3 tons of concrete are placed per person on earth and now I'm wondering how much of socialism you could reproduce by instituting a rule that you're not allowed to use concrete unless you can find some person to allocate that much concrete out of their 3 tons/year personal budget. Want to build a 2700-ton skyscraper? Better find 900 people to affirmatively agree they want that skyscraper built
