Would have to disagree with you on one thing...
Currency belongs to those who issue it. So, if you let others (e.g. government, central bank, etc) to issue currency on your behalf, then it belongs to them, not you. In bitcoin's case, although it is the miners who are the issuers of BTC, everyone can set up their own mining rig at any time. The biggest hurdle that must be overcome is miners believing that bitcoin is an investment asset. And that's why I'm here... to help them realize that bitcoin will die unless there are millions of transactions in the block chain daily.
Dude, being able to just flip a switch and print your own money is exactly why we have regulated monetary organization in the first place. It doesn't fucking matter that a central authority prints the money, it's still a proof-of-work instrument.
I'm not suggesting that printing money is the same thing as issuing it. In bitcoin economy, the amount of money that can be printed is set at 21,000,000BTCs. Miners (a.k.a. central banks) only have the power to issue that money into the economy by putting their own bitcoin reserves into circulation; then it becomes the job of bitcoin users (a.k.a. member banks, or just banks) to circulate that money around the economy. The more the miners or users hoard their bitcoins, the harder it becomes for the producers to generate sales (hence, they will jack up their prices, and the economy will experience an inflation). As you can see, if miners/users want the economy to grow, they must keep spending.
Furthermore, inflation is a economic INCENTIVE to innovate, invent, and expand. That's why I believe people who stash away cash and bitch about inflation deserve to have their money divested from them, because I believe everyone should always be looking for ways to actively improve theirs and other's financial situations.
I'd say that inflation is more of an economic incentive to imitate than to innovate/invent. Think about it, why should one focus on coming up with something new knowing that by spending less today--in order to copy an already successful invention--one will be able to rip the benefit of higher prices down the road? Essentially, in the inflationary economy, the innovator/inventor's hand always feeds the copycats. The key driver of innovation/invention has always been and always will be a potential increase in the number of innovative competitors.
