It's really not, as evidenced by the fact that paying for what you use is how almost every physical good works, and many professional services (a lawyer's time).
It's fine for you to dislike the model -- I dislike it too. I don't like that it makes me anxious about consuming the next small unit of <whatever>. But there's nothing inherently counterintuitive or punitive about it. It's the simplest and most defensible payment model possible.
