What is significance of the ninth amendment

Hi there! So, here are three reasons for the 9th Amendment:

1) It limits and enjoins the federal government from usurping or making illegal these rights.
2) It restates the basic theory of government, that rights come from the people to the government, not that rights come from the government to the people.
3) It maintains the rights retained by the people.

Hope this helps, and have a great day!
