> Earth can’t afford for everyone to routinely hop on a jet-fueled aluminium cylinder and fly ten hours at a time.
Flying is expensive enough that it's already not something that everyone does routinely. And once we get electric planes, then Earth will be able to afford that.
> we decided incorrectly that we needed to travel one time-zone per hour.
That wasn't incorrect. I'd rather put up with some jet lag than for all of my travel to take several times as long.
