I always ask myself how the blockchain would work with physical products. Isn‘t there always a human who needs to either - enter the data somewhere - put a tag on the product - scan a tag and where they could, knowingly or not, produce false data?

Yeah this is the fundamental problem, the only benefit you get with a blockchain is you know the data hasn't been altered from the original but there's no guarantee the data originally entered was correct. All the pitches about tracking shipments have the same issue, shipping companies already do most of that without blockchain and the main issue of people lying to the computers isn't solved by adding a chain to the mix.

  Why is blockchain needed for that and not any other immutable ledger?

    It’s not, but if you say that you’re also saying that the people who’ve already put a lot of money into the system won’t get rich reselling their tokens.

    It's not needed that's my point, the proposals for blockchain in most instances are best served by a WORM database and even that doesn't solve the actual issue of lying to the machine. The proponents all have a vested interest in something making their tokens worth while or at least bringing in new money so they can actually cash out. That's why NFTs exploded they were a great way to bring in new real money to allow people who were *coin rich to cash out to real usable money.

    Because a blockchain can operate in the presence of even large and powerful malicious actors. The issue here is a social/regulatory/legal one. The current international shipping game is a cartel business, and the cartel doesn't want competition - so they can use government, brand recognition, etc to maintain their moat. It's not that the blockchain version isn't clearly better, it's that the getting there part is a very difficult and tricky process.

      Who is incentivized to mine a produce blockchain? How are tokens immutably assigned to units of commodities in a way that can’t be compromised?

  Think the idea is to use economic incentives rather than legal incentives, e.g. lose a bunch of money if caught cheating. This allows new participants to compete better across jurisdictions.
