That's fine for small, tightly controlled networks.
We're talking about millions of computers under the control of

Nowadays most people don't have one strict role. They do work for

Spooks are a small part of the US government networks. And even they

Yea, I'd love to be a ruthless dictator as well.
Maj. Gen. Richard Webber, commander of Air Force Network Operations,
issued the Dec. 3 “Cyber Control Order” — obtained by Danger Room —
which directs airmen to “immediately cease use of removable media on
all systems, servers, and stand alone machines residing on SIPRNET,”
the Defense Department’s secret network. Similar directives have gone
out to the military’s other branches.
An August internal review suggested that the Pentagon disable all
classified computers’ ability to write to removable media. About 60
percent of military machines are now connected to a Host Based
Security System, which looks for anomalous behavior. And now there’s
this disk-banning order.
The order acknowledges that the ban will make life trickier for some troops.
“Users will experience difficulty with transferring data for
operational needs which could impede timeliness on mission execution,”
the document admits.
It could get tricky if these security measures cause mission execution problems.
People could be dying while the data is kept secure.
Security is always a trade-off.
And, of course, in the end the US military can only secure its own
computers, which is only part of SIPRNet.
