Dropping containers at the consumer end isn't that bad, at least when they're empty they're not that hard to move back on a truck and there are plenty of uses above scrap value for a container in seaworthy condition.

It's actually strange that we don't seem to have any system for just dropping containers at the destination until the contents have been processed, instead of the current system that essentially mandates unloading the container rapidly as soon as it shows up because an entire truck+driver is waiting for the unloading to complete.

For palletized loads it's easy to unload them into temporary space in the building they're delivered to, but not everything is palletized.

There are big forklifts for taking containers off trucks and stacking them. Some recipients buy in bulk, store for later use, and stack their own containers. But most distribution centers want to get the contents into pickable inventory and start selling it.

The US military does a lot of container stacking, because they want reserves, not a "just in time" supply chain. "Moving Mountains", by Gen. Gus Petronis, covers this. He handled logistics for the Gulf War.
