Firstly, I think you meant prOscriptive,
I'm fairly confident I mean 'prescriptive'. Like in prescriptive vs descriptive grammar.
(..)in addition to the attraction of rock music, namely Elvis and the Beatles and the rest is history, no mystery!
There are more reason English has become de facto standard in international communities (especially the scientific one). While what you wrote is one of the reason for its popularity, it's not only because that.
(..)would you keep your passport in as orderly, clean and presentable condition as possible, or rather all dog-eared and dirty?
Language isn't a physical thing. Also, language evolves constantly. The day Brits (or Americans, but I somehow doubt they would try to do it) would create something similar to RJP would be a sad day for the English language.
Only you can answer that...yet somehow, I already know unfortunately what the answer will be.
I bet your ass you know it.
