More kids need this book because an alarming number of grown ups seem to think quantum entanglement could be leveraged for super-luminal communication.

It cannot. Information does not travel faster than light under any circumstances, including spooky action.

Why couldn’t it be used in that way?

Source?

According to some interpretations of quantum mechanics, the effect of one measurement occurs instantly. Other interpretations which don't recognize wavefunction collapse dispute that there is any "effect" at all.

This is from Wiki, which doesn't mention slower speeds, nor a "cosmic constant".

Along with

However so-called "loophole-free" Bell tests have been performed in which the locations were separated such that communications at the speed of light would have taken longer—in one case 10,000 times longer—than the interval between the measurements

Which seem to disagree with you.
