If such a system existed the benefit would more likely be at the manufacturing end rather than final delivery to a consumer. You could have artisan manufacturers making everything to order using a distributed system of parts delivery. This would allow smaller firms to hold very little in stock, and deliver much more quickly. Final delivery of a product like a phone is much simpler than the supply chain of all the parts.
