That logic has a glaring flaw, that while tulips might be in short supply, the price is driven by everyone else doing that too, so there'll be a glut of new blubs in the future, so the future price shouldn't be assumed to be the current price.
Anything self-replicating can't hold to "current price best predicts future price".
The Hunt Brothers (re)learned this with silver in the 70's. (80's?)
what happened with the silver rule 7 is different from the tulip craze.
Hunt brothers buy a bunch of silver, lots on margin (bank borrowed), government saw what was happening and literally changed the rules of the market to force them to mass liquidate when they couldn't meet a margin call (all of the sudden). https://en.wikipedia.org/wiki/Silver_Thursday
