Jeremiah,
Could you refine your question? Here is what I think you are asking:
Hulsmann says a marginal reduction in consumption results more resources being available for investment. In contrast, there is the Keynesian paradox of thrift (which has been debunked in the Austrian literature.)
You present a scenario of deflation without a central bank, with banks operating as money warehouses or accepting time deposits (no fractional reserve lending). Thus, the deflation you describe will not be the destructive type encountered with a credit system collapse. The type of deflation you describe is the good type that results from increased productivity, the result of capital investment. Consumers will have the pleasant effect of an increase in purchasing power over time.
Imagine saving money for 40 years, and the purchasing power remains intact or actually increases! Our only experience, due to the central bank, is that of the purchasing power of our savings being wiped out over our lifetimes, making us wards of the state, dependent on social security (I digress, but this does show the seriousness of the problem).
There is no reason to believe consumers would hoard money into oblivion under such conditions (unhampered market). Sure, some would hold off if they think they can get a better deal later, but there is nothing unusual about that, they are following their own subjective value scales and will exchange their money for goods when they subjectively value the goods more highly over the money. They is no reason to believe they will prefer to starve to death or go without goods of all kinds because they will get a better deal later.
“Gee, the purchasing power of my money is increasing, I better NOT spend it”. That just does not make sense. Now, if one says “I fear losing my job, so I better save and not spend”, then that does make sense. To call such behavior “hoarding” is ludicrous.
The hoarding is the result of the consumer reaction to a credit system collapse (central bank induced boom gone bust). Of course they will save when they fear losing their jobs, etc. Why would I buy a house now when I can buy one a year from now at a lower price? The current housing deflation is not the result of unhampered market conditions that you describe in you example. The destructive deflation we are experiencing now resulted from the previous Fed intervention.
Are you getting stuck by not recognizing the distinction between the two types of deflation?
