I'm a huge blockchain advocate, but I 100% think this is an important point people need to understand. The blockchain is a great solution for pure digital assets. Its an awful solution for physical stuff.
I think this is a holdover of thought from bitcoin. Bitcoin wanted to be a currency for our real world economy. It never became more than that for many reasons. ETH (and now more modern chains) have become more than currencies. They are digital economies. Physical items are foreign goods in a foreign jurisdiction the local economy has little control over.
Even within crypto, different L1's are like foreign economies, and moving assets cross chain is complicated.
