It’s not friendly advice, that’s the point! Businesses don’t typically like it very much when someone makes their supply lines double-digit more expensive overnight. He’s putting companies on notice. He’s doing it with language which will get the statement widely reported (and unfortunately mis-reported). But carefully reading what he is actually saying, you can see he’s not actually ordering anything. That’s the point. In your hypothetical example you would need to change two things. One, it would read “All my relatives are hereby ordered to starting looking at flights a day early...” And two, you would have to be God, because in that example you would be the one controlling the weather.
