How do I supposed to make small payment when the fee are literally equal to the price of the product?

I'm buying a game key from a marketplace and the price listed is $5.50, or 0.0014 ETH, but the network fee (recommend) are $7.71 or 96 gwei. Why is it so high?

What is the lowest network fee that the transaction will go through?

If I'm paying via Coinbase Commerce, do I really need to pay such a high network fee?

How is Ether supposed to replace fiat as a mean to make everyday payments?
