You apparently don't know how this is actually done in modern times.

Empty plastic bottles take up a lot of space, and that wastes warehouse room and costs extra money to ship. So nobody makes bottles in one plant and then ships them elsewhere to be filled.

Instead, they make what's called a pre-form. It has the threaded neck of the bottle already molded, but the main body is not finished yet. Those are what are shipped to the bottling plant in sealed packages which is easy and economical because of how small the preforms are.

Then, once in the bottling plant, the same machinery which fills the bottles with water expands the preforms to their finished size. Nowhere in the process does a big empty bottle sit around gathering dust. They are filled literally seconds after being formed.
