According to john locke, people sacrificed a portion of their freedom and consented to be ruled in exchange for what?

I believe the answer is: the government's protection of their lives, liberty, and property.

For example, due to the existence of government, individuals have to sacrifice our ability to establish businesses however we like. But, in return the government would provide law enforcement if there is other citizens who had bad intentions toward us.

i want to say death; parole, probation, and fines are still being used all the time.
