Precisely.

If there were anything inherently wrong with it, you would have to ban most family businesses. Just because some forms of something are undesirable, and a corporation out of laziness/practicalities enacts a general policy to ban all forms of it; that does not make the entire thing morally reprehensible automatically.

You know how this whole conversation thread started with my saying "the only case where a boss should be sleeping with an employee is if they have a pre-existing relationship", such as being married?

Yeah. We're circling back to the original statement. A sure sign that the conversation is no longer productive.
