Sorry, I don’t think requiring to use dscan can be called a specific effort, compared to what miners need to do just to NOT be taken the moon materials. Plus this is really not a protection, miners can’t expect it to actually prevent or reduce the efficiency of a gank.
hu … no ? I mean in the context of the game, tangible would mean assets .
perceptible by touch.
“the atmosphere of neglect and abandonment was almost tangible”
The only tangible thing moons offer to miners is ore.
Well this is why I said moon mining is useless. You have to put more assets on the table, to be more organized, to schedule on a specific day one week before, only to be able to harvest less worth 
I think people who keep doing it just don’t have a clear vision of their return over investment.
