Human's don't accurately measure risk, and society doesn't allocate resources according to minimizing deaths in the cheapest way possible.

Lots of people die, likely many more due to shoddy work on the drive to / from the airport. As a society we could probably save far more lives with far less cost by say changing tire grippiness standards / mandating people get their tires inspected.

The Boeing stuff is just for the most part moral grandstanding. Everyone drives around all day every day in cars that are far less safe than a 737-MAX without worrying about "reassuring those who died".

Worse yet, we let people ride bicycles to work which are far more dangerous than cars.
