In your extreme example of EV above, sure you should take it, that's a once in a life time spot. Lol. But let's be real here...
The question was not whether you'd take that bet or not, I know you would. Just as I know you wouldn't take a bet of $1 on a coin toss if the potential winning was $0.10.
The question is WHY you would/wouldn't take such bets if it's not for their positive/negative EV? If you refuse to use the term and calculation of EV for one-time bets, then how do you assess whether a one-time bet is worth taking or not and what do you call it?
