Yep! this was my realization when I first started thinking about the idea. You can't computationally trust the movement of physical stuff. Some amount of trust is going to slip in somewhere. It's better to insert the trustless transactions in the places where the relationship is purely digital. In my example above, you have a large vendor which you (as a retailer) trust has inventory to back up every NFT they minted, and you trust to ship relatively reliably. You can't avoid that trust (though you could build mechanisms to increase your trust like 3rd party audits or something). But the relationship with hundreds of small retailers could be built trustlessly. So it's more like strategic trust as opposed to pure trustlessness.
