There is another reason that cashless society is awful that was not talked about in this article, but I think is just as important - a digital dollar means that you have a dollar where it is impossible to commit crime. While that sounds like a good thing (who wants crime?), it very much stops being a good thing as soon as you bump up with laws that go against your morals. Designing systems with the assumption that we will always have democratic and free government is a horrendous idea, allowing the government to have a complete record and log of every single transaction you ever make, as well as having the ability to stop you using digital money, makes it so easy for fascists.
