Humans are dumb.
Not all of them, mind you, but enough that it's honestly a surprise we as a species have survived for as long as we have.
Over and over again, we share stories of terrible tragedies, horrific accidents and bloody massacres that explain why certain rules or precautions get placed.
But then some dumb upstarts believe such measures are excessive and get rid of them...and then get immediately reality checked so hard that the original measures get reinstated and the bill to repair or replace everything comes in and makes life a million times more expensive.
Preventing a tragedy is a lot cheaper than repairing and replacing what was lost, but nobody ever thinks that.
And the people that do get made fun of or worst.
Then again...I suppose some people actually plan to profit from such tragedies too.
I know I do so by accident.
