Yes. It would totally matter that the he has money, airport is nearby, everyone speaks English and are super helpful, etc. How could those things not matter?
No. He didn't wake up in another country, that isn't how hypnotism works.

I think you should watch it again and pay attention to what actually happens through the lens of what is possible and legal, meanwhile make a list of all Derren's lies and misdirection in the piece.

He's an Illusionist. Nothing more. He is creating an illusion.

He often does simple magic tricks that I know how to do. They do not require any mentalist patter to perform but he always presents them as if they do because that's his schtick. It's very lucrative schtick for him. His illusions are compelling. Without it he would just be another boring magician.

Remember: if a magician tells you how a trick is done as a part of presenting it, that is not how the trick is done.
