Yes, hi Sprolf. I robbed your ship because you were in a 100k shield Agama with no escort. You presented a fat target with 50 million in cargo ripe for the taking. So myself and my mate helped ourselves to some of it.
You'll note your ID allows you to do the same to me. In fact most of the mining IDs now come with an interesting balance of hijinks and limitations. If your DSE mining ship comes up on a mining site in Liberty and you spot my Miner ID ship squatting it? You can grab my stuff and tell me to get bent.
Furthermore the mining ID cannot land on any of the mining corp's bases (DSE excluded). So if you chase my mining ID ship in, say, Omega 11 I can't evade you by landing on a Daumann base.
Its a give and take thing.
So here's the thing. The Miner ID allows me to yoink ore. I can do the exact same thing with a Junker ID. Not only can I do the exact same thing with a Junker ID but I can do it with more powerful ships.
So, all in all, it's just a little tip of the hat to provide an extra element of fun and realism to the territory/resource wars between established groups and dirty straw chewing miners who refuse to sign on with any group.
Or think of it as my dedication to urging miners to consider hiring security to watch over their mining sites. For the coin I stole off your ship alone you could have hired the entire reaver merc co to escort you 10 times over.
