Barter is "natural", but so is tribalism/centralized governance, and monopolistic practices. Yes, it does have to be "we'll do it better/smarter this time" for both governance and the market-based economy(not "free market"). Thinking that dismantling it all and allowing "free" organic growth won't lead right back entrenched interests and gatekeepers within the government and market is naive.
The answer to this is not to double down and give the state even more power to pick winners and losers, thinking that "this time will be different" or "we just need to get the smartest most moral people into power".
