Privacy could potentially be engineered to some degree. Someone could devise a way to do business in which we simply aren't capable of spying on our customers.

Privacy could potentially be engineered to some degree. Someone could devise a way to do business in which we simply aren't capable of spying on our customers. It wouldn't be easy, laws would definitely help, but it could be possible. Freedom is another matter. The government would be useless without sufficient force to compel anyone (or corporation) to adhere to the laws. To remedy abuse of that force against freedom, as you say, we do need laws. Something like a contract that says "you can have plenty of force to compel any one of us, but if you consistently violate these agreements, then we may join together with enough force to overpower you". Maybe it could be done with some amendments to the constitution. We could call it something like a 'bill of rights' or something...
