The name MF/HF/VHF etc were defined by ITU v.431 originally in 1953. Amateur radio operators in the 1950s commonly were using “shortwave” frequencies (now referenced as HF commonly). As it’s been told to me from multiple operators in that era, the naming scheme used by ITU for each group is based on the amount of bandwidth available in each group, not based on any presumption of AM radio broadcasts being used as a baseline.
My point is that the basis for the designations were made in a period where AM radio was the primary use case for radio and so frequencies higher than the AM radio band are called "high frequency," whereas today those frequencies are actually much, much lower frequency than nearly all forms of radio communication.
