We Should Have the Right to Buy/Sell Stocks w/o SEC Watching

Imagine that every time you went to the grocery store, convenience store, bookstore, or hardware store, those stores — under government orders — sent a complete, itemized list of what you bought and when you bought it to the government and organizations working on its behalf that could challenge you to explain any purchase that catches their interest. Or imagine that the manufacturer of your car, at the behest of the government, set up a direct feed from your car's GPS so the government could interrogate you about any of your travels.
