Yea, I get it. But IRL there is a lag. And that Lag causes problems. There will be a certain number of things sold at one value before people get around to repricing the products, their will be an affect.
Just like the minimum wage joke: They raise the wage, so product price will raise overtime to eat the increased cost, and then everyone is back to the same position. The time between those two positions there is an affect on the economy.
Tell everybody they will make 50 bucks and hour; they love you. But then the cost of products go up to counter the inflated wages.
The losers are people with contracts that don't cover changes in CPI (Consumer Price Increases). Like mortgage and car loans. It will help the consumer but kill the business. All the Big Boy contracts put in the CPI clause. The "little guy" mortgage and car loans are covered in surprising ways. A little secret. Yea, the amount you pay on your loan will stay the same, but I bet you a 100 BitCoins that the insurance on those loans go up. Guess what, You are forced to carry insurance on Cars, and Houses until you own them. The Big Boys are good at hiding the details.
Have you see a loan market in bitcoin? Not really.
Well, I was one of the first to be loaned with bitcoin once to go shorting. I shorted once, then I try to short again..but I gave up and paid all my debt(with a positive inflation rate!)
Anyway, if the loan market is really small or non-existent, than loans aren't really a problem in the bitcoin economy.
