Privacy-wise, GNU Taler is like cash:
When you pay with Taler, your identity does not have to be revealed. Just
like payments in cash, nobody else can track how you spent your electronic
money. However, you obtain a legally valid proof of payment.

Thanks to the proof of payment, the purchased good can indeed be delivered
anywhere close to your home (I believe Amazon proposes such a system in
France, for instance) and you can prove you are the buyer, while remaining
anonymous.
Now, shipping to the address of a friend is fine too: not only it does not
help building a profile of your friend (like you pretend) but it turns it
harder to build a profile of your friends: she (probably) does not want the
product, you do. In other words, that practice generates noise in the data
used to build the profile.
I am pretty sure Stallman would tell you all that too. He uses the same kind
of arguments when he justifies why he sometimes asks people to lend him their
cell phones.
