Also, because first class is smaller, you spend less time standing in the jetway and airplane aisle.
Part of the annoyance of boarding isn't just the total time it takes from when they open the gate door until when it's done. It's the amount of standing up, holding your luggage, shuffling forward a bit, and wondering when the person in front of you will move.
Use driving as an analogy. Suppose you get out of a doctor's appointment at 3pm and are meeting someone to see a movie at 6pm. During those 3 hours, the only two activities you can do are kill time on your phone (either lingering in the doctor's office lobby or sitting in the movie theater lobby) and drive. Do you leave at 3pm and avoid rush hour, or do you wait until the last minute and get in traffic? Either way, you're going to wait 3 hours, so you're not saving time, but one is less stressful.
Yes that does sound nice and I agree that the first option would feel better. However if someone offered me the choice between being able to do the first, and say, a new Macbook Pro 16", I would take the computer every time. I think even if I were a billionaire I would rather keep my few thousand dollars and suffer the indiginities of economy, but of course I'm not, nor can I know how my values would change if I were a billionaire.
If you fly a lot on long hauls, you'll quickly succumb to economy class syndrome if you spend all your time there. Once or twice a year, it is now problem, but not being able to sleep very well for 11 hours straight gets old quickly, and there is only so much content to go there in their entertainment system (if you are a frequent flyer, you've seen all of it)...not to mention your butt and legs just start getting sore after awhile.
Even though I'm not really a frequent flyer, I generally buy business class when they are on sale. E.g. Beijing to Bali on Hong Kong Express for $900 roundtrip (vs. $500 for economy), or Beijing to LA on ANA for $2000 last minute one way (vs. $1500 for economy, and since I was moving, it was tax deductible at the time). You can find some good deals, especially in Asia, and the experience can be worth it.
Boarding first doesn't need to justify the full first class price difference. It's a small peel in a pricey bundle deal that includes much better perks.
