Completely agree on the "potential" part. Bitcoin is revolutionary indeed, but its potential its still unrealized.
Going back at the two personal examples I gave you in my last posts: the company with which I did business in Argentina in the past, would never pay me in BTC at this stage. The process to buy significant amounts of BTC its still too lengthy, complicated and shady, especially for a big company - the volatility risk is also too big ATM. As absurd as it sounds, right now the only solution would be the one I was proposed, which was to fly to Argentina to pick up a suitcase full of pesos (an alternative would be dollars bought in the black market, but that is too risky and thus out of the question for a legit company trying to transfer a big amount of $).
On the contrary my friend in South America is using BTC to move some money back and forth, but still he couldn't make his relatives to understand how to safely "cash out" without my help.
Making a long story short, the potential is all there but the current infrastructure its not good enough to realize that potential. Bitcoin *can* be a revolution indeed, but it still has a long way to go.
What I do not agree with is with the statement that BTC being decentralized and trust-free is only "ideological" stuff with no utility. No sir, not at all. Those characteristics has the potential to solve very real, daily problems for millions of people on the planet.
The company in Argentina can received in btc and use future market to secure its value(plus 500 or 796 ).. thus Volatility can become not a problem for them.
And it is also a problem that MT.GOX even thought as a largest liquidity method but it also sometime can't meet the needs, there are other way can solve this problem out by invent a trader that use fixed exchange rate to dealing with large transaction.(often 2-3% below the market average) Then this company can sold its BTC separately by small quantity over different exchanges.(Not only can make profit on the transaction ,it also release liquidity and price pressure on those exchanges)
So, the potential of BTC is numerous, all problem of its either liquidity or volatility can be perfectly be solved...
