Mm for instance, I think in some contexts markets are pretty powerful, like prediction markets are pretty good at predicting things. (Not saying they're flawless -- polymarket likely overpredicted Trump's victory). Or that benign-looking regulation is frequently detrimental to the public -- while not libertarians at all, Abundance makes a good case for repealing a lot of regulation related to construction. Such regulation is often motivated by people who want to preserve the value of their homes, even though on the surface it appears to be about environmental concerns. (Obviously, I think the environment is important, so we shouldn't just repeal everything. Just that we should be more critical of such regulation.) Another example is how the U.S. banned civilian supersonic aviation in its airspace because of disruptive sonic booms; apparently the technology now exists to keep such booms very quiet, but the regulation persists, because it's not booms which were banned but instead supersonic speed as a proxy for booms.
