> It is bad for several reasons. The easiest to grasp is that people tend to keep their money in their hands (hoarding) if that money is acquiring value by itself. If people don't spend their money, or lend it, the economy suffers.
What I have never understood about this argument is people can't eat money, they can't sleep under it, they can't do any number of things with it. What they can do is buy things, like food, which allow them to do the things they desire. Having a deflationary currency is pro-citizen, it is pro-poor, and pro-middle class.
These classes are primarily uninterested in "investing." What they are interested in is saving. Saving to go to college, to buy better accommodations, to go on a vacation, to stop working two jobs, etc... They have no interest in complex inflation protection vehicles.
You may say: you are being silly, you don't understand how the financial system works! Maybe I don't, but neither does a large percentage of the population. Shouldn't our default policy always be about protecting those most vulnerable? Those most likely to be exploited? Are we doing that now? Would a deflationary economic system be to their benefit? I think so and so did the creator of bitcoin.
