The message needs to be useful to the audience. Timing is important. Sometimes, how you dress influences the message, and sometimes, the scenery matters.
Nonsense could depend on the audience. You might suspect that this picture implies that there is no audience. On the other hand, you are now the audience. Ok, you’re saying, yes, maybe, but this message was written before you came to it and became the audience.
Another thought would be that making sense is the burden of the author, not the reader. Makes sense to me!
