I think that saving money for both unexpected problems and future investments is an important part of social responsibility, and I would not adopt a currency that was deliberately designed to make saving difficult unless it was forced on me. Even then, I'd probably try to turn it into some kind of commodity that I could sell again later in order to dodge the losses.
There are a few assertions on the main page that I find interesting, in particular the one about money value vs goods value being "the underlying cause of the boom/bust cycle." I don't have time to read the linked book about it, is there a quick version of the explanation?
