Re: Would have been helpful...
Actually, I would MUCH prefer if Amazon or anyone else would have no idea who I am each time I choose to enter into a transaction with them - you know, kinda like how shopping USED TO WORK for the previous few millennia or so. Stores used to have no idea about my name, address, previous purchases*, or the detailed origin of each banknote and coin I use to pay with**; and that's exactly the way I fucking like it. Just because the nature of modern online commerce is what it is, and just because some folks already see it as the normal way of things, I feel no obligation to cease looking for any and all ways that would maintain the privacy we all used to enjoy by default, in the digital realm as well, if possible.
* Please consider that while fidelity cards and such do exist here around me as well so far I had zero difficulty in simply never asking for or agreeing to accept one.
** I also had zero difficulty so far in paying exclusively with cash for anything I buy, except for international online purchases.
