Tell that to Sri Lanka. There is massive unrest, because people will starve. The farmers were not the ones saying, "don't use chemical fertilizer", the ex-government was.
The transition can't be forced. It is a paradigm shift in land management and an entirely different skill set. You can't just tell all farmers they cant use fertilizer anymore without teaching how to do without. That is how you get famine.
Regenerative management is more profitable for farmers so it is going to happen regardless of what governments want. You just can't force it.
That's extremely misleading. The (still current, power is mainly in the president who is refusing to leave) government banned chemical fertilizers on an extremely short notice, with no planning. That's just incredibly stupid.
Had it been planned, with subsidies, education, multi-year transition, it probably wouldn't have ended in a disaster as it did. But anyways, that's not the only reason for Sri Lanka's demise (lots of stupid money wasting in useless infrastructure, lots of corruption, and Covid). It was just lots of incompetence from very stupid people.
