Maybe we should rank our "have to"s on a scale from 1 to 5, where for example:
- "objects in motion have to (1) remain in motion unless acted upon by an external force"
- "humans have to (2) eat food to stay alive"
- "developed countries have to (3) maintain a scientifically literate populace"
- "university PR people have to (4) write like that to pay for food and shelter"
- "university PR people have to (5) write like that to afford a new sports car"
I think you meant something like the example for (4), but reasonable people might see it more like (5), and in both cases it's at odds with the more fundamental "have to" (3) for society.
