When something is that drastically different, it becomes different in kind. For example, if you have high network latency, you cannot jam (play live music) with friends remotely. If you have low latency, you can. Just because the difference is in a single value (I.e. net speed) doesn’t mean it doesn’t change the fundamental nature of what’s possible. Air travel makes the kind of business, shipping, and attendance possible that wouldn’t have been possible otherwise, because our collective lifetimes and risk tolerances are limited.
I think you're saying that there are businesses that rely on cheap air transportation that are very valuable, but at the same time couldn't afford higher air fees.
But that's a contradiction. If they are valuable, their customers would pay more for their services - that's the definition of valuable. And if their customers would pay more, they could afford higher air fees.
No, all I’m saying is that air travel is so different than any other kind of travel, that it is very special, and borderline magical. Saying something like “nothing magical about air travel, things and people would still travel around the globe” is very reductive. I’m not giving my opinion on subsidies.
That doesn't mean we should subsidise it.
I’m responding to a claim that there’s nothing “magical” about air travel. It literally enables things otherwise impossible.
