You are putting it bluntly.

If I wanted to exaggerate, I could also claim that the corporate travellers with a travel policy that allows them to always book domestic F and international J are most likely to make FF status but hardly get any benefits out of it (as they get most benefits through the premium cabin class anyway).

No, I think it's more complicated in practice. The guy who makes status or earns a lot of miles through non-flying activities still enjoys flying and has some usage of the status and the awards. If he didn't value any of the incentives the programme provides, why would we partake in it?

To go back to the analogy, it's the same with the guy flying premium cabin for business travel. His behavior can still be altered because, besides his business travel, he likely has use for award miles when traveling with his family, he may make use of his status on family trips in eco etc. etc.
