...and everyone that owns (is "enrolled" in) AAPL is "incentivized to get other people to buy" Apple products. So Apple is a "pyramid scheme" right?
"Pyramid scheme" is a real thing with a real meaning. Someone posting "BTC to the moon!" on Twitter does not make BTC a pyramid scheme. Typically people are describing market manipulation, and they just don't know what a pyramid scheme is (your post).
