Guns, we understand that you like there to not be consequences for people doing stupid stuff, but as I said, once you get past a certain level of proficiency, you got to take things off 'easy' mode, and at least go to 'normal'. Sure, don't start people off on 'hard', but never moving off 'easy' just cheapens the setting. This is not a nice world we're talking about here. Things can go from shiny to hell in a handbasket at the drop of a hat. Getting screwed by the Johnson (or the world in general), having the consequences of your decisions come back to bite you, and finding out that you just royally fragged yourself are all part of the setting. Without it, you're doing as much a disservice to the setting (and your players) as if you decided to play Twilight, the RPG, and call it Shadowrun.
And no, Common Sense should not be automatic. Look around you. There are plenty of people in the world we live in right now who have absolutely no common sense.
