Obvious
The reason to obfuscate NOTAMs is to give me an advantage over the lowly ground based Luddite. Otherwise why bother spending 45 hours doing a PPL if it was all in plain English and easy to understand?
Why would I need 45 hours of PPL training if the AIS website was as simple as clicking points of where I'll be flying and it giving me the briefings I need?
It's the same reason why we obfuscate IT and build redundancy into laptops. Otherwise there'd be no IT industry and we wouldn't get paid vast piles of cash for pressing a few buttons every day!
