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.
