Without encryption backdoors, how will you know if people are illegally using high-strength encryption? Everything must be decrypted on demand to determine if i

  That doesn't seem hard: just make sure everything is plaintext (i.e., a known and approved protocol, like FTP, telnet, HTTP/HTML, etc.), or make sure it's an approved encryption protocol that has a built-in backdoor (and the data within, again, being one of those approved protocols). Of course, people could be hiding high-strength encryption within the backdoored protocol, but they could do random checks for that. Basically, the only way to really hide data is to either use steganography, or to use an unapproved data-transfer protocol (and using unapproved protocols can be banned).
