If you are employed you should petition your employer for tools you want. Maybe you can use it to take the day off earlier or spend more time socializing. Or to get a promotion or performance bonus. Hopefully not just to meet rising productivity expectations without being handed the tools needed to achieve that. Having full-time access to these tools can also improve your own skills in using them, to profit from in a later career move or from contributing toward your own ends.

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.
