What makes you think they're going to stop with pallets and "some packages?"
They have designs for chips to be hidden in the soles of shoes, or in tags, or woven into the fabric of clothing. They have readers designed to be hidden in floor or ceiling tiles.
Each chip has a unique number, that individually identifies that individual product. The visionaries set aside enough bits to individually identify every consumer product projected to be produced for the next several decades.
Boxers or briefs? Bra size? In the RFID world that the visionaries see, that will no longer be a personal question, it will be promptly broadcast by your underwear to anyone with a reader, with present technology up to 100 feet away.
If one purchases their products with personally-identifiable means, such as a credit card or using a store discount card, that individual piece of underwear will be tied together for someone with access to the proper databases.
So not only will the stalker pervert hacker know that the pretty woman walking down the street is wearing a pair of pink Victoria's Secret Lace Tanga nylon/spandex panties, size medium, and a white Second Skin Satin seamless unlined demi-bra size 36D, he can find out her name, her address, and when and where she bought each of those items using which credit card.
How does it add power to the state?
Each individual set of items, even if not tied to a specific individual (purchased with cash, say), generates an individually-identifiable pattern of information that can be used to track specific individuals.
So for example, say there's a meeting of the Tibetan Liberation Front in the back room of a dimly-lit pizza joint. Suppose the government agent sets up an inconspicuous RFID scanner, and records the data of everyone who walks past it in the vicinity of that meeting.
They now have a map of connections between known and suspected associates of that organization, including the guy who went to the back room looking for the bathroom who's wearing Fruit-of-the-Loom size 36 briefs and a beige Tommy Hilfiger polo shirt under his jacket, and is carrying a packet of peppermint Certs in his pocket.
Suppose they set up the hidden scanners in the surrounding vicinity, like the ones being marketed to track shoppers as they walk through a store. Even if they don't know who Mr. Briefs/Polo Shirt/Certs is right away, they can track his movements by tracking the individually identified items he is carrying.
No more need for inconvenient checkpoints and paperwork inspections...
With RFID, people can be tricked into adorning themselves with all the unforgeable data the busy totalitarian needs to run an efficient oppressive State.
Have you heard about the way new color printers are encoding their serial numbers with a pattern of barely-visible tiny yellow dots on every page they print? HP and LexMark are RFID-tagging their printers, so that the serial number can be registered to the purchaser and point of purchase automatically. If you're a cranky government official who wants to target a modern-day samizdat for elimination, voila!
Ask yourself, why are the manufacturers so opposed to RFID-tagged product labelling? What do they have to hide, and why are they trying so hard to hide it?
