Everything you say sounds nice in theory, but I don't buy it in practice.
So Amazon is going to send me a USB with a huge one-time pad?! You mean the same way my bank securely gives its public key to me on a USB when I sign up for an account? (Hint: they don't.) And I'm going to carry around multiple USBs for every large company I interact with?
And smaller 'mom-and-pop' stores are going to rely on an Internet-wide key distribution center (KDC) that everyone will trust and is going to send USBs to 75% of the US population?
And active attacks are going to be prevented how, exactly?
One technical mistake:
Large amounts of compressed data can have a very small footprint these days.
Of course, if you're talking about using a one-time pad then compression is out of the question...
