I do not necessarily accept the premise that consumerism is necessarily good or bad but I do not find the argument that a currency that discourages economic interaction is a good thing very compelling. I do not think that having someone else prepare a meal for you in the evening, lets say, once a week is "useless hole digging" but and honest exchange of services for money. Drastically changing the dynamic of such interactions seems like a pretty wild economic experiment, not one to be taken lightly.

When spending within the economy is restricted in this way by market forces value will concentrate very highly in essential goods and infrastructure and attracting rent-seekers to those areas of investment. The net result, it seems to me, is casting off the tyranny of fiat currency for a new kind of tyranny. The same kind that lead to the trust-busting era in US politics.
