You can't have it both ways. If you accept one death per airshow or one Shoreham per year, then you accept it. If you decide that something needs to be done then you have just accepted mission creep.
That doesn't mean you can't look at the incidents to see if something small could make it even safer without losing anything, but at this point there are no easy fixes. All the easy yards went decades ago.
We are well along the road of diminishing returns into the part of the graph where huge efforts produce negligible gains in safety.
If you feel the need to make aviation safer after every incident, then you might as well just cut out e intervening stages and ban flying because that is the logical conclusion of requiring ever increasing amounts of safety.
