Speculation is the least of bitcoin's problems. I think a crypto-currency is inevitable, but it'll be one that has a mechanism in it to inflate and deflate to match the demand for currency in the market. During a boom there's a higher demand for currency and the supply must increase if prices are to remain stable, otherwise deflation is going to happen in an amount that matches the boom; that's not stable.
Who cares if prices stay stable or not? The value represented by whatever price is attached to those things won't change

Everyone who understand economics even a little bit.

People aren't paid in value and they don't spend value, they're paid in currency and they spend currency and they all care that prices are stable because their paychecks aren't going to suddenly change.
