Usually is probably correct- I agree most/many markets are perfectly well served by a free market but my argument remains that some markets require government involvement and if left to 'free market' are vulnerable to cartels, cronyism, rentseeking and damaging effects on the wider economy. A contemporary example of considerable significance and effect that I have given elsewhere on this thread is the rare earths supply chains. Free enterprise alone has not not been adequately incentivised to invest and compete in this market meaning government involvement is required unless you want to become hostage to Chinese supply chains.
