Would I be right in suggesting that it's not encrypted data unless someone can decrypt it to prove so? In other words, we're free to send garbled nonsense to each other.

I'd think not.

England will imprison people who forget passwords. Here are two examples:

I was thinking something less obviously encrypted than a usb stick with a dialog box saying "Enter password" - how about steganography? "A password for my image?"

Does this also include using something like ephemeral keys?

It depends where you live. In some countries you are required to disclose an encryption key when required to do so by law enforcement:

.. and if there is no key then you may be in a very difficult position.

Civilization should have collapsed the moment a large group of people agreed that one element should disclose a specific piece of knowledge, or face punishment. If everything else if my life fails, I want to become a martyr to this cause.

I've rar'd quite a few files in my day, many with a password. The majority of them I could not remember if asked. We effectively have made forgetting a crime in the name of protecting children and stopping terrorism.
