What if the other party you are doing business with decides to publish your private information? It's an unforeseen circumstance that should be addressed.
How do you punish someone for publishing your private information that you put in the public domain? Do you make it a crime to use any information in the public domain? Do you extend the copyright laws to include private information placed in the public domain? Or do you look at this as a civil case where damages must be assessed?
Getting government involved only grows government, sets up agencies to regulate the sharing of information, provides government with an additional portal into people's lives, and for what? Because twits don't think through the possible consequences to their emotionally driven decisions.
Exactly. Lots of people want a lot of information or else they won't do business with you. Disclosing information for the purpose of a specific transaction shouldn't be interpreted as a lack of interest in the privacy of that information. It also galls me when, in the guise of being good corporate citizens, many companies will release your personal information to law enforcement on the strength of a request, unbacked by a warrant. Warrants discourage fishing expeditions and tailor the breadth and depth of the investigative authority to match what's justified by the probable cause. The steps are there for a reason, they're not some anachronism, and these companies are outside their rights to waive OUR rights to information we had little choice but to trust them with for a specified or implied purpose.
