Why wasn't this on the outside of the box?

The following found in the instructions of the portable basketball hoop we purchased for the Adventurers for Christmas. We had no idea...

"Do not attempt to assemble this system without reading and following all instructions carefully. Failure to comply with any of the warnings in these instructions may result in serious personal injuries such as cuts, broken bones, nerve damage, paralysis, brain injury or death. Failure to comply may also result in property damage and will void warranty."

Should we have purchased the more expensive model? Or maybe this is why we don't usually shop at Buy'N'Large but generally stick to the Bullseye.

9-1-1 dialed into the phone as Danjo the Magnificent and King Carrot (aka Grandpa L.) attempt the assembly. 

Did I mention that certain steps in the assembly process are also irreversible? Would that be the death, or brain injury?

Edited to add:

After encountering more warnings on page six, referring back to the previously quoted warnings on page two, King Carrot and Danjo the Magnificent are now claiming an adrenalin rush, saying this may be the most dangerous thing they have ever done.

I am expecting The Doctor to arrive at any moment.
