I'm not disputing that. I'm just pushing back against the casual suggestion (not by you) to just go spend $200.

No doubt that you should ask you employer for the tools you want/need to do your job but plenty of us are using this kind of thing casually and the response to "Any way I can force it to use [Opus] exclusively?" is "Spend $200, it's worth it." isn't really helpful, especially in the context where the poster was clearly looking to try it out to see if it was worth it.
