You're correct, but also forgetting the best part. The ratio between width and length stays the same!!

This specifically is what allows easy up-/downscaling for an A* size.

I guess the key thing actually is that the width of A(n) is the same as the height of A(n+1).

How often do you need to scale up or down a printed document? I don't see how that is useful.

You may want to print multiple pages per sheet.

By hand? Surely it would be faster to click a button in your word processor, which supports letter paper.

Print shops nearly always print multiple copies/multiple pages of a job onto larger sheets and them cut and collate them afterwards, as the print step takes the longest time which includes moving sheets in and starting the print and then stopping the print and moving the result out.

An A1 sheet can fit 4x A3 posters, 8x A4 pages or 16x A5 flyer/booklet pages without any wastage, so all you need is a single A1 printer.
