Any computer with sensitive files should have them encrypted, or preferably have your entire hard drive encrypted. They should also be backed-up in case the computer is lost, stolen, destroyed, or seized.
If a person or company keeps sensitive files on an insecure computer, then that company/person should be at fault.
If you send sensitive data over the internet then it should be encrypted. If not, then companies, governments, and other organizations could easily grab that data.
In reality though, there are millions of completely insecure computers and devices which carry data that could harm companies, individuals, or governments if compromised. Educating the operators of those machines and ensuring that they properly secure them is very difficult. The best method would be to have hard-drive level encryption on all devices, make sure people know how to properly backup data, and to educate people that they can easily say, "I don't know the password, I'm suppose to call my IT manager after I arrive at my destination and he will provide the password."
