I mean, they're not as unobtainable as you might think. There's only a million item password combinations on the V6 - okay, a million is a lot, but it's a smaller number of combinations than previous versions and quite a decent portion of those are taken up by working passwords. It takes a decent amount of luck but it's not that hard to get the destiny stars by using trial and error. It's still not that easy, but if you pick a good starting point you could literally be getting now-unobtainable or otherwise entirely unused items in a matter of minutes. In my experience? Picking a number in the 900s for the first three digits and cycling through the last three digits can quickly get you items.
