George Pazin,
The medical analogy is a good one, because it differentiates an option in theory from an option in reality.
It shows the absurdity of arguing for remote or far fetched possibilities.
Another example would be for me to bet you that you can't walk across a 50 foot long, 4 X 4 piece of lumber.
As it lies on the ground or two feet off the ground, you'll take my bet for $ 20.
But, if I elevate that 4 X 4 off the ground, you'll start to have your doubts. At 50 feet off the ground, 250 feet off the ground and 1000 feet off the ground, you won't take the bet, for any amount. Why because it magnifies the consequences for failure, despite the fact that nothing else about the physical challenge has changed. It's still a 4 X 4, it's still 50 feet long, but, the real world consequence of electing to walk the 4 X 4 at 1,000 feet eliminates the option to the prudent person, hence the viable option doesn't exist.
If you are a PURIST when it comes to playing golf, you can relate to what I'm saying. If you're not a PURIST you won't.
P.S. Scrambles aren't golf.
And, neither is the driving range.
