You might value it differently, though.

The company also would be giving you money if they, e.g. , gave you sets of annual Disney tickets, or a family membership in a luxury gym.

That's the whole point - there's an unlimited amount of potential outcomes that your original hard limit doesn't cover. Of course your final decision can be targeted towards "net value to you", but fundamentally, you can only assess net value once you have the facts.

Your hard limit becomes "I'll quit if I don't like it". Which, really, you don't need a "hard limit" for.
