Responding to the part you added later: the question is not simply having individual use value, which one could argue that prostitution has, the question is whether labor transforms matter into merchandise or not, in short, whether it produces or not value (having value and producing value are different things).
(Paintings, Movies, TV Shows, Games etc) shouldn’t be included either because there is no tangible value being created.
No, there is tangible value being created. You take the combined work of everyone involved in production and end up with a commodity. Paintings, Movies, TV Shows and Games are commodities.
