If you remember aaaalll the way back to 2005, a whistleblower at AT&T in San Francisco made public the NSA's secret wiretapping program. Despite ongoing lawsuits brought on by the EFF, it doesn't seem like the majority of the public really cared at all.
Seems like most people simply don't give a shit about their rights.
One could also say that the slippery slope didn't obtain. Disclaimer: I was outraged at the time, but have yet to see the men-with-guns at my door.
The only people who *need* privacy are those who are a) doing something illegal or unethical and want to keep others from finding out or b) doing something competitive and want to keep their progress from their competition.
People in category (a) deserve no legal cover for their actions.
In other words, "People who are doing something unethical deserve no legal cover for their actions." 'Unethical' may be defined as "belonging to a class of activities that my peers and I disagree with or find distasteful." Your argument, and the fact that many others have similar positions, actually makes an excellent case for privacy.
