> They were building simple fairly short structures that can only really kill you if the roof hits you on its way down and gave a whole lot of warning before that happened.
So, you don't believe roofs were invented until very recent times? The only building I've ever been in where roof collapse couldn't be fatal is my neighbor's chicken coop.

Easily disproven. Here's one refutation:

Seriously: your lack of knowledge about historical architecture is impressive.
Yes, I'm generalizing. Yes, I know that opens my up to low effort "but exceptions" comments with a looking down one's nose town from you and your ilk. No, I don't care.
A barn is a lot more forgiving than a tilt up Walmart. Castles don't pancake like the Surfside Condos (which gave a ton of warning BTW). I think it speaks volumes that your example is a rotted floor overloaded beyond it's capacity. This stuff isn't rocket science except in the rare cases when it is. Anyone trying to portray it as such is doing a disservice to society.
