Another thought is that at HF frequencies, a inexperienced or poor
operator can propagate their signal over the whole world.

Under the right conditions, yes.

If I were to
be making a training ground for amateurs, it would be using line of
sight type signals

I disagree!

The greatest sustained period of growth in US amateur history was from the
end
of WW2 until the mid-to-late 1980s. From 60,000 hams on VJ day to about
600,000
40 or so years later. And this included a period of almost no growth in
the mid
1960s. Through most of that time, the training ground for new US amateurs
was
predominantly HF.

I agree with Jim's historical view. The advent of reliable VHF/UHF with
digital readouts and digital frequency selection at reasonable prices is
what ultimately opened up the significant amateur use at VHF and above.
The addition of repeaters also contibuted greatly to the VHF UHF
increase in operations.
