Lots of good ideas... Below is my take, which approaches the introduction of bitcoin from a macro-economic "the current system is broken" standpoint. I read zerohedge somewhat often, and I believe this fits very nicely with the existing economic consensus of the zerohedge crowd, and also has the benefit of not requiring an up-front in-depth explanation of bitcoin. Obviously there is A LOT to potentially convey about bitcoin; far too much for a single introductory article. Positioning bitcoin as the solution to the current broken fiat money system seems like the right approach to me. The ZH crowd should agree with the background thesis by default, and therefore be, at minimum, intrigued by the theoretical notion of bitcoin, hopefully enough to look into it further:
Better Money
As the world deals with $200 trillion in debt, with most "advanced" economies relying on a democracy-fiat system that represents a one-way mathematical function toward a debt spiral, it is obvious to many that our current worldwide money system is broken. The current run to US bonds is not a flight to "safety," but a flight to the current "lesser of evils." Politicians from Greece to the US promise more and more while allowing the free market to produce less and less. Rational people are seeing that the crash of '08 is a mere precursor to the ultimate and inevitable worldwide sovereign debt disaster. A better system is needed.
A better system starts with better money. Money that doesn't give election-cycle prioritizing politicians free reign to promise the world to the masses while delivering nothing but debt and inflation. Many advocate a return to the gold standard in order to tie politicians' hands, while others propose various revisions to the Fed and other central banks. However, as is often the case, the market itself has developed, and is increasingly embracing, a powerful solution that's growing from the bottom up: bitcoin.
Consider a monetary system that offers perfect information. A system that broadcasts its intentions to the world with mathematical perfection. A system whose formula cannot be manipulated by politicans (or anyone, for that matter), thereby eliminating the entire notion of monetary uncertainty. A system that offers what gold and other classical "hard money" offers: limited supply, divisibility, portability, homogeneity, recognizability, durability...but which is also fit for the modern electronic world where funds zip across the Internet and most money is simply an account entry "in the books."
Sound too good to be true? Perhaps. But while none of the world's debt problems have been solved and while Mr. Bernake contemplates buying up yet another round of Uncle Sam's bonds, the bitcoin experiment quietly grows, rejecting the entire theoretical basis of fiat currency and a politically-controlled elastic money supply.
Bitcoin is a decentralized, mathematically fixed-supply currency. Through its use of indisputable cryptography, it has made possible, for the first time in human history, a money supply that cannot be altered by any central authority. It is also fully designed for the modern electronic era. Sending funds internationally no longer requires a hefty wire-transfer fee, several hours (if not days), and transmission of sensitive identity and account information through an insecure electronic banking system. Senders and receivers of bitcoin can be anywhere in the world. People can quickly, easily, securely, and psuedo-anonymously send bitcoin to each other over the Internet from myriad devices (computers, tablets, phones, etc). Bitcoin is how money should work in the modern economy.
The bitcoin experiment is young, and its future is unknown. But it doesn't take too much vision to see that, like the fledgling Internet of the late 1980s, it has the power to disrupt the status quo like few innovations before it. Control of money need not be in the hands of government. The Internet democratized and decentralized information. Bitcoin democratizes and decentralizes money.
