>Given the fact that cw is far more spectrum efficient 

It isn't. Spectrum efficiency is bits/Hz.

HF packet is about 0.1 bits/Hz. HF CW  is about 10bits/sec, and needs about
50Hz to allow for fading etc, so is about 0.2 bits/Hz. Analogue speech is
often reckoned as about 2 bits/Hz.

CW is inherently narrow band, not spectrally efficient.

It's also a skill, and arguably an art form. Just as you protect rare
animals to prevent extinction, there's an argument for treating CW the same
way.
