Stealing is not a word that applies only to physical objects.
Funnily enough in some legal systems it does. Where I live the legal definition of “theft” is: Taking away a movable thing.
Stole the words right out of my mouth!
Please provide an example of an action legally considered "stealing" that does not involve stealing physical objects.
Any word can be applied to any concept with any meaning thanks to the fluidity of vernacular.
Language is all just sounds and markings. Anything can be redefined to mean anything, and anyone can decide to aggressively assert their preferred definition of a word.
