That would be awesome! I hadn't thought much about making more realism to the occurrence of minerals. But I think the one thing there we almost all have noticed is that gold ore is too abundant in the game, and it would be cool if servers could adjust the amount of gold ore independently of the other minerals.
you can space the power available ,for instance the wind mills and be spaced out to spread the coverage area as the power blocks seem to interconnect, space them 20 blocks apart in a straight line and you will have power the entire distance.
I probably wouldn't have that technology available right away, because in the real world it took us a while to really figure it out (and it's still not perfect), but I definitely agree that adding scrubbers to the game would be a great idea!
Some of that is possible. I may be wrong, but I think it's possible for more than one mint to be made, for instance. As for the ignoring laws, currently that isn't possible, but the criminal justice step on the road map would make it possible for people to break the law, and thus make law enforcement necessary.
