Discussions like the current one make me wish we had huge but relatively affordable space habitats [1]. People with a radical idea for restructuring society [2] could pool their resources, build/buy a space habitat, and prove that their way is superior to the status quo (or fail miserably, or something inbetween) [3]. This way, empirical evidence could be collected, and radical ideas could be tested and adopted if they turn out to be beneficial. The best way to convince others is to demonstrate an implementation.

Unfortunately, this is not possible on Earth, because pretty much every square meter is already claimed by some entity, but there's virtually infinite room in the solar system.
