The trust venn diagrams I think aren't quite as bad as you describe - there are a ton of people with gmail accounts who implicitly start from a position of trust with Google, but I'd wager a lot of them wouldn't trust "border guard from a random country" to have unrestricted access to their personal gmail. They don't really need to care about VPNs either once across the border, https access to gmail.com is all they need.
