Isn't that just a social version of the precautionary principle?
You can never be damn sure you can build a better world without trying unless you are sure you can simulate that world ahead of time, and you can't be sure of that without validating your simulation. I personally suspect this sort of simulation is simply impossible because of well known "chaos theory" type phenomena like feedback loops in real systems. There is no way to A/B test history.
We now know that Marxist type systems of the sorts deployed by Lenin and Mao don't actually result in a better world and in many cases result in a worse one, but I don't think anyone could have proven such a thing ahead of time had the systems never been tried.
In practice the precautionary principle would lead to a world of absolute stasis since if the burden of proof is 100% on the actor then no action can be taken.
My personal view is that the ideal situation is a stable society with a frontier. That way you can go to the frontier and try new things and then the stable society can import the things that work. This isn't unique to me, and a version of it is called the Frontier Thesis. We once had this in the American West, but no more, so we should hurry up and build more rockets.
