> I mean, what's the idea, having a button for every single product we buy?

It's a button for every repeatable commodity buy you make. Most applicable use cases are: toilet paper, detergent, cleaning supplies, certain groceries. In other words, it eliminates pretty much all friction to ensuring that you're always stocked with those products. You're right to be skeptical, but even just reducing a small amount of friction to buying means better convenience for the consumer and more money for Amazon.
