Separately, many are business spenders. Spend $100k, much of which will get reimbursed. But the fee is out of pocket.
Additionally, many of us carry multiple cards with relatively high annual fees, so if all your fees add up to, let's say $3000 a year then we are looking for ways to reduce that number or at least get the most benefits out of it. It's about cost versus benefits.
