I see. I was under the impression that mass drivers can be made relatively accurate since the NSS' old mass catcher design had a 100m mouth. I've been using these as references (https://settlement.arc.nasa.gov/75SummerStudy/Chapt5.html)) (https://space.nss.org/colonies-in-space-chapter-6-the-moon-miners/))

How so?

now the only case that sort of makes sense for shipping unrefined materials is luna--->lagrange point so you can build space colonies. Because A. lunar regolith is a fine construction material especially for things like a colony's radiation shield and B. luna's gravity and day-night length makes it difficult to use solar

Even then, you need a mass driver on luna and a giant catchers mitt ship to intercept big regolith pellets. But planet to planet YOU DO NOT SHIP ORE!

Now one thing you might ship are volatile elements. Places like the moon or mercury are pretty low on volatile elements like CHNOPS
