No point to gold if you never use it. People will be encouraged to save and spend on the things they
need, and stop buying junk they may or may not want. Problem with a depreciating currency, you're inclined to spend it sooner, rather than later. With a depreciating currency, Joe's gotta work his whole life to make ends meet. And if there's no work left to do, Joe's up shit creek, like Joe is right now, and he'd be further up the creek without a paddle if Mr. Obooba decided to pull most soldiers and bring them home; then there'd really be no jobs. So the war keeps going with fiat contributing to the reason why there must be war in the first place; war creates jobs, and lots of them.
However, war is such a waste. Yes, it creates jobs, but what's the point of a job when all you're doing is destroying, just so you can build all over again? That's the magic behind fiat; you're a slave to it, until you manage to store up enough to ride the rest of your life on. So wherever the jobs are, that's where you must go, and if that job is warfare, that's that. Cash that works like gold suddenly looks much more attractive; considering work is becoming a thing of the past now that a single machine can replace an entire factory of workers with a few guys to run the thing and make sure it's working right (heck, machines are even replacing soldiers now), people need to save up now more than ever. Fiat works when you live in a nation that must be constantly worked on. But everything's pretty much there, now. We have the infrastructure, we have the cities and the towns and the schools and the electricity and the Internet in several different forms, we have the parks and the farmland and the machines to run that farmland, we've got almost all the work done to live comfortable lives. Everything's going to hell because we're still stuck to this depreciating currency, and nations can't expand any more than they already are. Soon we'll have to colonize the moon, wage a war against it, destroy it, then colonize it again, just to keep jobs flowing.
Sorry, I think that was slightly off topic
But the point is, a currency like Bitcoin is exactly what we need right now; something to use sparingly, for necessities, and maybe then life will look up a bit. There's nothing stopping someone from going hungry with 10k bitcoins sitting in their wallet--that is, unless they're a miser. But they probably deserve to die if they're so cheap, they won't even buy food for themselves.
