That phrasing is part of the problem, not the solution. You're conflating the idea of a manufacturer (Proctor & Gamble in this case) with a reseller. Amazon tells you both, but since the retail products are (should be) identical, neither they nor you really care whether or not this particular box came from "Joe's Nutrition" or "Sally's Supplements", and worrying about that distinction is like arguing against the fungibility of money (did that dollar bill in your pocket, which you got from an ATM, "come from" your job or your side gig?).

It's not the comingling that is the root cause here, it's the fraud. It doesn't matter whether or not Amazon buys their pills from Joe or Sally, what we care about is that they're not selling fake pills. Focusing on comingling seems to be missing the point. We have even less ability than Amazon to detect the fact that Joe is selling fake pills, so they'd still make it into people's mailboxes.

Sounds like it is time for a "Falsehoods Programmers Believe About Retail Products" with the first entry being that every item with the same SKU is identical to every other item with that SKU.

You would think at the very least Amazon would need to maintain a chain of custody for each individual item that is meant for human consumption. What happens if there is a Tylenol poisoning [1] like scare with one of these supplements? Would Amazon legitimately have no way to track down the source of the contaminated product? If they can, what would be the possible explanation of not displaying the source to the user beyond "it is cheaper if we don't"?

It's not just products for human consumption that can cause injury. A shoddily made counterfeit phone charger can start a fire and burn down your house.

That's an interesting argument except for the fact that the source of money is extremely important for fraud and tax purposes. Money laundering is specifically the co-mingling of "inventory" to hide the source. Amazon is product laundering.

When the product comes from "Sally's Supplements" then if there is an issue with the product then that's first and foremost Sally's problem. It might go up to Procter & Gamble or maybe it doesn't get that far.

The source of the product and who supports it is very important.

Counterfeiting is going to happen. Typically you deter it by detecting it and punishing the counterfeiters. Commingling defeats this. I guess we can make Amazon inspect everything they receive from third party sellers thoroughly enough to reliably detect counterfeits themselves, but that seems much less likely to happen.
