We really need to re-instate some assumption of a reasonable level of common sense before it's too late.
If a person can't assess for himself the risks involved in running down a cobbled street carrying a frying pan, or appreciate that if his flight lands on its' belly there are going to be some complications, then surely they are destined to have a hard life whatever happens.
With luck they will remove themselves from the gene pool before figuring out how to procreate, and will therefore do us all a favour. Why does everyone else's life need to be dumbed down to a level that allows them to be protected?
