No offense but isn't this basically saying "There's no point explaining things to people or attempting to change their minds through dialogue".
"It is difficult to get a man to understand something when his salary depends upon his not understanding it."
--Upton Sinclair.
You're making the assumption that people are operating from a position where they're open to having their minds changed, and not firmly entrenched in their current mindset (
or actively trying to propagate that mindset) specifically due to sunken costs or greed.
Changing minds through dialog is good, but it requires the other party to be open to dialog, or to having their mind changed. When there's a financial stake in them staying ignorant? The game's already against you. That's why I specifically said they'd retreat to those nonsense speculative rejoinders.
When you're already on the hook it's not about interpreting new information and changing your mind, it's about justifying your prior investments and hoping to make it out with a profit.
I wish logic worked on people who are already heavily into NFTs, but in the last year I've never actually seen a case of that working out.
