Why was the need of government so important once farming and trade increased?

Surplus crops drove down prices, so the government tried to reduce surpluses by limiting the acres that farmers could plant in key commodities while, at the same time, guaranteeing a certain price for those commodities.

Explanation:

It didn't work because farmers became more productive on the acres that were left and surpluses persisted.
