Better technique is safer, all other things being equal. But of course, things aren't equal. There is something to MGA's point.
Being better means fast carved turns on those easy groomers, which means you are headed towards the trees if something goes wrong. A terminal skidder goes pretty much straight down the middle, switching from one edge to the other when he "turns".
For more challenging terrain, I sometimes wonder if upping your game means you progress from situations that feel dangerous (at your current skill level) to situations that actually are dangerous.
I'm not backpedalling on better equals more fun, though.
I agree only partially with your contention that improved skill levels get one into deeper sh*t. I think what get most skiers into real trouble is that they are skiing at the limit of their ability level. Whether they are beginner, intermediate or expert. The up side of skiing at the limit of one's ability level is a sure way to induces the adrenalin rush that most of us called "FUN". The down side is one is a hair away from disaster.
Most of us won't drive 10/10 normally on the road knowing that a sneeze could land us in the weeds with dire consequences. So why do it while on skis? More fun?
A good number of skier get their fun thru the adrenalin rush produced by treading at the limit, near misses and link recoveries. (My favorite term from Ghost). The odds will catch up with you some day.
Better technique, better tactics, better understanding of our own ability and limitations will allow us to expand our performance envelope in a controlled fashion so we can ski at a high level, have fun and still have plenty of reserved safety margin - for when the sneeze happens.
