Back when you couldn't buy most idSoftware games here I had to go out of my way to let an online buddy of mine with a non-German Steam account buy and gift the collection to me. So it does happen. And I even got quite some duplicates as I had managed to buy some, just not all of them.

TBH personally I find that a much more convoluted reason. It might be an edge case of "I will watch this clip of horrible person to get the original source" but actively seeking out material for free just so that they get nothing, but I can consume it in whole? That sounds really rare to me.
