There is no point in a constant and 100% predictable inflation. Every hour (or even second) the price of goods and services will have to be changed accordingly! Is that what you want? A madhouse?
There will always be inflation or deflation with bitcoins too. And the inflation being slightly predictable helps a lot.
Complete nonsense. This will encourage people to spend their coins for real money like gold and silver. Because real money doesn't inflate!
That's what people are doing with fiat currencies too. I don't oppose people who are spending their coins for gold and silver, but those aren't that widely accepted, be it b&m store or an online shop.
