Physical stores can be (used to be) big vending machines. They accept cash and give receipts as a proof of purchase and can (usually) be found in the event of issues. They're probably recording you on camera in case you steal or use counterfeit money, but vending machines probably are too. I think the real problem is doing the same thing at a distance. At a store you know where to find the entity you purchase from in case of issues and you get a receipt at the same time you purchase. You can sort of get the same thing with an individual face-to-face, but only if there is an established trust in some form (buyer has to trust they can find the seller if something goes wrong, seller has to trust buyer isn't using counterfeit money, etc). It's pretty hard to trade at a distance without revealing something about your self. At the very least, there's going to be a middle man that will want to know something (a lot) about you if they're going to provide you services (P.O. Box, shipping company, etc). They want to make sure customers stay honest so they don't get in trouble when customers scam each other or make an illegal trade. It all comes down to trust. I think all the retailers, on and off line, are blatantly violating that trust when they sell our data off, but not enough people seem to care or have a better alternative, so there are no consequences for retailers. New law is usually the last thing I want to see, but it seem to the only way to introduce a consequence for sellers at this point.
