yea, their bandits, they rob and steal for all kinds of people, some of them may have had glass/orcish/ebony/whatever. it's no tunrealistic to think they actually may have found some during their bandit raids on whatever trade caravan or city they have attacked. and who's to say that the bandt cheif you just found isnt also a master smith and has been crafting himself and his bandits some stronger gear?
altho, the better stuff (ebony/ daedric) would probabaly be best ob Bandit cheifs, while hte other types of bandits go to orchish maybe.
The point brought up is that if 1) he was a master smith and able to make ebony/daedric, he would be a rich dude living in a mansion rivaling the Gray-Mane running the Skyforge. And 2), if he found it, he's a poor bandit and would sell it and make enough to live on for years.
Bandits. The concept of a bandit is poor. Do criminals steal cars to use for themselves? No, they are stolen to sell. That's more of the point.
But the great thing about modding is you can have it your way, and we can have it ours. So it doesn't matter to me much how you envision it. We can both co-exist with our ideas.
