Not sure if you posted your video above for MA or not, but your zipperline skiing is would represent pivot/skid. Almost zero shovel pressure until you slide into the mogul sidewall below.
Way to get after it though, at some point you should try to turn into that pile of snow instead of skidding into it.
The locals at that ski area have mastered the rotary turn. I don't think there's an ounce of carve in some of their lines. It's an amazing display of skill and beautiful to watch. They create extremely tight lines that can only be met by matching their style, tighter lines than I've seen anywhere. A bunch of them will loop a single line, and it's a challenge to follow it. Some of my failures to follow them in lines just forming, where there isn't enough bump, have motivated me to work on flattening my skis and swiveling them back and forth as fast as possible. So, I love the challenge of holding the line in all it's different forms, sometimes that's pivot skid, sometimes not. In any tight icy line, you will be faced with the choice to windshield wiper turn or go way too fast, in other words pivot or not ski the line. You seem to have little respect for any skiing that involves pivoting or skidding and have chosen not to ski the line, and I probably have a similar view for any skiing that avoids the line. Different strokes for different folks.
I believe this style is suitable for many east coast resorts. We get very little powder, very little tree skiing, crowded slopes, little vertical. What's left to do? Try to follow impossibly tight turns. It's a challenge and fun. I think if we threw you on some generic east coast bumps, devoid of powder or packed powder, you would find that your style is completely no fun in those conditions, and you'd leave wondering how in the world some of those locals get through it so smoothly. In some of those lines if you turn into the bump, you've just broken your ski or something worse. You are a fair weather bump skier. If you ever end up in a place without such nice conditions, I would recommend embracing the pivot skid rather than quitting bump skiing.
