Sure but it is also about storage and density. Oranges have peels and don't stack that well and can be damaged. Extracting the value into a mostly rectangular container allows for the same product in an easier to distribute form factor. The old tubes of concentrated orange juice took that to an extreme by also removing most of the water and freezing them.
They also homogenize the flavor of juice and concentrate by stripping the oxygen and then adding in brand-specific flavor packs at the end. This doesn't have to be reported as a separate ingredient because it all comes from oranges. [1]
Allegedly orange juice in the grocery store was invented in the mid 20th century as a way to sell more oranges.
