However, the Latin phrase was specifically coined to refer to a legal principle on how the justice system operates, not to the more general sense that ignorance doesn't protect you from the natural consequences of your decisions.
So what? Google says the following about Shakespear's "rose by any other name" line:
"A rose by any other name would smell as sweet" is a popular reference to William Shakespeare's play Romeo and Juliet, in which Juliet seems to argue that it does not matter that Romeo is from her family's rival house of Montague, that is, that he is named "Montague".
But you can use it as an idiom to refer to anything that the meaning applies to.
