Why do countries create guidelines and laws on how a country is going to be run?

L aws are rules that bind all people living in a community. Laws protect our general safety, and ensure our rights as citizens against abuses by other people, by organizations, and by the government itself.  We have laws to help provide for our general safety.  These exist at the local, state and national levels, and include things like:

Laws about food safety.  At the state and local level, health departments have guidelines that restaurants follow for how to store and prepare food in a healthy manner, so that diners won’t get sick. At the national level, the Department of Agriculture and other federal agencies inspect food production plants to be sure that the food that shows up in your supermarket is safe to eat.

Speed limits and traffic laws exist so that we drive in a safe manner.

Licensing for doctors and nurses ensures proper training of the people who look after us, and who often have our lives in their hands.

Countries will make guidelines on why they're run to either protect the interest of the people or protect the interest of the ruler/dictator/whoever is in charge.
