This is the right answer. Collecting, retaining, using, and selling all this crap should simply be illegal. For Google, for Amazon, for Target, for Visa. Any of 'em.

The more pragmatic libertarians ought even be on board with this, since even if they don't care about massive corporations having all this stuff, allowing its collection gives de facto access to it by the government, and you can't effectively opt out even if you take extreme measures like not communicating with anyone except over encrypted comms and not having any kind of cell phone—you are still in pictures others post to social media, for example, or mentioned in others' unencrypted messaging/email conversations, et c. Your only hope is to become a hermit, basically, which is unreasonable.
