Well, we can debate this until the cows come home, and it won't change anything. The regulations clearly allow singles, and thus they will continue to fly. The FAA will not change the requirements on this.
I'm willing to bet that the 'rat-killing shuttle' didn't involve a hundred takeoffs. I've flown fields where 200 per day was the norm. That won't happen in a 212. I'm not saying I enjoyed doing that, but it happens here, and it will continue as long as it's legal, which is likely to be well into the foreseeable future.
It's certainly true that there is a wide disparity of operators in the GOM, and it should also be noted that there are probably more helicopters flying out there every day than even exist in all of Europe. With that number flying, it's no surprise that there will be more incidents.
