The armor also wasn't impervious. It did absolutely nothing against ion blasts. That makes it entirely useless as an anti-piracy measure. Micrometeorites aren't a problem thanks to shields. Accidentally crashing into a star should never happen.
There are other ways to protect yourself against ion blasts, yanno. And even if not...
Okay, so the pirates have ionized the ship. Now what? How are they gonna get in? Cutting through the impervious hull - nope! Ripping the door off? Too bad the bolts that lock the door and the door itself are made of the same stuff as the hull; that's never coming off.
What are they gonna do? Drag you inside a larger ship? You mean the kind of place where they wouldn't dare direct the kind of ion blasts at your ship that it would take to knock it out? Great, you just sit tight while they try in vain to pry into your ship, wait for the power systems to come online, and start shooting up their vessel from the
inside.
Gonna sit in space ionizing you until you starve? What will that get them, if you leave the ship locked up tight? Not a whole lot, really, and a lot of time wasted that they could have been going after other things.
Even if - and this is not exactly a big if, I'll concede - the super-impervious armor is too expensive to use on random cargo ships, you would still want to replicate it for use on very, very important ships - transports carrying critically important people, for instance. Your flagship, perhaps, or even just to armor your very best fighter squadron.
