You’re getting downvoted because of being flippant but you are right, by definition there exists a trade off between cost and any feature. It’s the least interesting trade off: if want more X it will cost more. There also is a trade off between any two features mediated by cost, if I spend more on X, then I can’t spend as much on Y. What are more interesting are inherent trade offs. Like the famous trade off between security and liberty seems to not just be mediated by cost.
