As opposed to the current system where it is impossible to save for retirement unless you ate at least upper middle class? ...hmm I'll take a system where the poor might be able to save for a few years of retirement.
The other thing -- and I am surprised you did not touch on this -- is that a deflationary currency is anti-consumerism. Why buy something when saving that money makes it worth more in a year or ten? And with bitcoin, you keep your own coins, you don't deposit them in a fractional reserve bank that uses it to stimulate business.
This is, of course, the so-called Paradox of Saving which is utter horseshit for regular money but might be applicable to bitcoin.
Switch disciplines to ecology.
This is what the Earth needs. We cannot go on consuming our childrens' futures. We must end our senseless consumption in the name of "progress" or the Earth will lose enough of its ecological web that we can no longer survive. Some say it is already too late. I maintain there is hope but we must adopt a more sustainable civilization or we will perish.
Perhaps a civilization built on an actively deflationary currency that encourages us to avoid spending apart from absolute necessities...
At the end of the day, the biology of deflation means our money more closely matched natural systems governed by scarcity. This is vastly more important to me than any economic discussion, even if you were 100 percent correct.
What do you think?
