I benefit quite a lot from not having to use cash. I pay all my bills with credit cards. That means I can do it remotely, taking a few minutes a month, without having to leave my house. Having to pay each bill in person, in cash, would be a huge cost to me in time and effort. And if the companies I'm paying those bills to had to have the personnel and infrastructure to support all or most of their customers paying in person, in cash, the costs of the things I'm actually paying them for would go way up.

Sure, if you're going out for coffee and you'd rather pay with cash, it's a hassle if the coffee shop doesn't accept it. But that just means you go and find another coffee shop that does. That's a very different issue than the issue of cutting off people's access to non-cash methods of payment, which is what the article under discussion is talking about.
