The state can obtain your financial records, your location history, your communications metadata, your browsing history, and virtually any other digital information without a warrant or probable cause, merely by issuing a National Security Letter or other administrative demand to the companies that hold this data (3rd party doctrine in the US). These demands often come with gag orders preventing the recipients from even disclosing that they've been served. You can be under total surveillance and never know it, with no judicial oversight, no opportunity to contest the intrusion, no recourse after the fact. This infrastructure never gets repealed, even if "your guy and your party" are in power. It just expands.
