Well, the whole point of encryption is that you can send your message through despite the fact that your adversary can see it.

Replacing that with a system where your adversary can't see your message, and neither can your correspondent, is a downgrade, not an upgrade.

That depends entirely on your application.

Could you give some examples of applications of encryption where the purpose is not to send a message that adversaries may see but cannot understand?

Encrypting data at rest, for example. (Depends on how wide your definition of 'send' is.)
