I don't disagree with this take. These days people get way too much credit for just finishing. Most people have the physical ability to finish something like this. They think they don't but it's really just a matter of pacing.
What they lack is mental toughness. But there is also a difference in mental toughness in the person who does it solo with drop bags or with minimal crew and something farcical like what Nick had (20 people pandering to his every whim on top of whatever he has coursing through his bloodstream)
