> Fair enough. But you use your own address and name to deliver stuff from the internet. Where is the anonymity in that? Or i am missing something?

Yes you are, you're missing the addition of a trusted party. I may trust someone I'm trading with to keep me anonymous, mail my order out, etc.

But what if I do not trust my bank to destroy the transaction and keep me anonymous if someone comes looking later.

You trust the first out of necessity, but you only trust the second out of convenience.

This of course only applies to physical products as electronic products can be delivered completely anonymously.
