The practical problem is money can buy comfort but not the feeling itself. My opponent might say cash solves stress, and fair enough, but I still think once basics are covered, extra money just adds worry, not happiness. I am not sure how to argue it better.

Imagine someone with plenty of money and still feeling empty at night, that seems to prove the point. My opponent makes a fair point and honestly I cannot argue back much better. Extra cash just seems to add worry for most people.

Imagine a lottery winner who keeps checking the balance and still feels flat. My opponent is basically saying the same thing, so fair enough, I cannot really argue back. Money buys stuff, not that quiet feeling, and I think that is just how it is.
