But, soon, the economics will flip. And, there will be money to be made from selling privacy. For instance, assume all credit card, phone, cable companies, etc. pool their data. For a monthly subscription, this conglomerate will keep your info (or parts of it) hidden. The default will be everything is knowable about everyone, except for those who pay a fee to erase info from their records.
Far more money to be made selling privacy than selling info. 4th amendment and all the rest is moot. Our info is held by private international companies who, eventually, will begin charging you to keep things hidden from others.
Really the bad part is that most people don’t know about or how to use technology to protect their privacy :-/
What's the purpose of having a government again?
