I don’t see a specific need of a “blockchain” feature for this usecase.

Uber didn’t need decentralization to coordinate drivers and clients. Aws/Postgres can handle the fault tolerance. FedEx already does this.

I agree, there is no need for a blockchain. But, that explanation is what has been proposed as the justification for using one.

I would counter also that neither of your examples are actually supply chains. FedEx is part of a supply chain, but only a single member. the chain includes the manufacturer, wholesaler, etc. Uber also doesn't have a supply chain with its drivers. It is not running a supply chain for that purpose, it is a marketplace.
