I&#x27;m still not sure about your claim that private information consists _only_ of &quot;information I don&#x27;t want anyone else to have.&quot;<p>You can share information with another trusted party and still have an expectation of privacy (such that the government needs a warrant to compel access to that information). Conversely, you can have information that you don&#x27;t share with another living soul, and the government can <i>also</i> compel access to that information - e.g. a warrant to search your private belongings. The standard for how the government can access your information doesn&#x27;t automatically change depending on whether you&#x27;ve shared it with 0 or &gt; 0 people.
