It’s that last point that seems to be so true. 10 years ago those who were buying up the right keys, for high dollars at the time, likely had folks scratching their heads in wonderment (like my wife is currently). The passage of time shows them to be way ahead. No one knows what the future holds, of course, but the long term play is solid in my opinion.
These two comments are right on the money! Stop complaining, buy what you want/can/love (supply and demand will always rule) and enjoy the hobby ! I have no sympathy for quick flippers.
