Can't sell the item itself? Okay, makes sense.

What about a downstream manufactured item? Such as a CC-NC STL, where you have since 3d printed it? You can't sell the STL, but what about the printed object? If not for profit, must you necessarily take a loss, or could you sell the items at-cost?

Or offering a CC-NC item for free, in the same place you are selling other products for profit? Where the CC-NC item may be acting as a "loss-leader" to get customers to purchase your commercial offerings?

Or giving everything away, the CC-NC item and all other items, but while representing a commercial entity who is doing such for marketing purposes with the end-goal of generating more revenue for the business?

I much prefer GPL/CC-SA licenses, they're much clearer where the line sits in regards to usage.
