But if you build a nice Bitcoin Company that will benefit from this trend, and go public, the public will flock to you (assuming you have a decent plan, and Bitcoins keep gaining in mindshare.)
I'm clipping your post but you make a lot of valid arguments. I think the biggest "infrastructure" Bitcoin needs right now is a reliable and secure exchange. Somewhere that will provide volume and liquidity while at the same time giving investors confidence that their funds (currency or BTC's) are safe.
The Mickey Mouse exchanges we have in operation right now are just not going to cut it. The first group to make a legitimate exchange will not only greatly increase Bitcoins chances of survival but likely make a nice profit as well.
I think MTGOX will be better than ever when it comes back. They are taking the necessary time it takes to properly secure their website, so the clowning won't happen again. I think its amazing that people think that bitcoins are "invaluable" only because one exchanger gets hacked. Look at the price on Ebay, Bitcoin7, Tradehill, and every other exchanger. It's almost like nothing ever happened. You know WHY?
BECAUSE BITCOIN PRICES ARE NOT PEGGED TO ONE EXCHANGER.
