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?
