You can use many encryption methods with email and the contents of them.
Sending a fax to another fax machine that is typically setup in a general office location to be shared by many not only opens your fax up to a much bigger potential audience but it also leaves a paper trail that then has to be properly disposed of. And you consider that to be more secure?
Perhaps, but it's much easier for an email to be intercepted, not to mention the fact that it happens to reside on servers that service thousands of users.
Additionally, encrypting email is not something most email clients do natively, especially from a copy machine, and require significant extra steps. These steps aren't likely to be handled well by administrative assistants.
There is a reason the government and corporate industry still use fax machines.
