No, benefiting is not sufficient. I benefit every single day from technology and capital I don't own and from products I have never bought. I've never used an oil tanker directly and neither have I paid for it directly. Yet, I benefit from oil tankers every single day, and it's perfectly ok. What would NOT be ok is if I benefit DIRECTLY from a product without paying for it.
If you borrow a Pen or Pencil from your friend to write a note, are you are committing a crime? You are benefiting from something directly that you did not pay for. If you write a novel with the borrowed pencil, does the novel belong to you, or do you have to share the profits with the owner of the Pencil. What if he lent you the pencil conditionally? He let you use it to erase something but not write something.
What if the pencil he lent you wasn't his pencil to lend? You had no right to write with it.
You get the idea.
