"I have nothing to hide, so I have nothing to worry about."
The 'nothing to hide' argument misunderstands what privacy protects. Privacy is not about hiding wrongdoing — it is about maintaining autonomy, dignity, and power over your own life. You close the bathroom door not because you're doing something illegal but because some things are not for public consumption. The same principle applies to your medical records, financial information, political beliefs, search history, location data, and private conversations.
Data that seems harmless in isolation becomes powerful when aggregated. Your grocery purchases reveal your health conditions. Your location data reveals your relationships, your workplace, your doctor, your therapist, and your place of worship. Your search history reveals your fears, curiosities, and vulnerabilities. Data brokers combine these streams into profiles containing 1,500-3,000 data points per person, which are then sold to insurers, employers, landlords, law enforcement, and political campaigns — all without your knowledge or meaningful consent.
Historically, surveillance has been weaponized against people who did nothing wrong by the standards of their time. The FBI's COINTELPRO surveilled Martin Luther King Jr., anti-war activists, and civil rights organizations. The NSA's mass surveillance programs, exposed by Edward Snowden, collected data on millions of Americans with no connection to terrorism. When you say 'I have nothing to hide,' you are trusting that the current government and every future government will never consider your lawful activities suspicious. History suggests that trust is misplaced.
