I believe the answer is:
- If the government abuses its power, people's natural rights are taken away.
- The government has a responsibility to protect people's rights, not to control their lives.
- A government is empowered by the consent of the governed.
The preamble prefers that the power within a society fall to the hand of its people. Because of this, they tend to factor regulations that would diminish government's influence in civilians'private life and created several branches in the government to divide its power.
