Yes exactly! My yardstick for the "spiritual" health of the internet is how easily I can have two devices across the internet communicate without a service in the middle. It shouldn't be difficult in theory. I _can_ send a file from my phone to another friend's phone via ftp for example, but only if both are on WiFi, have port forwarding turned on on the router, and either just have the most up-to-date dynamic IP stored, or are using dynamic DNS, or have a static IP allocated from their ISP, which is less common at least here in the UK. If you're using a cell tower, forget it.
