while the tying up does not help to buy goods and services with BTCs, we can use it to our advantage:
BTCs is the BEST INVESTMENT !!!
Just look at the rally over the past 3 months +1000%
I am going to buy more now!
Irony? The rally was primarily on Mt. Gox, and you can't get any money in to Mt. Gox to buy BTC for. And what happens to your funds if the current rally was financed by fraud and Mt. Gox loses?
If I were mtgox, I would freeze all BTC bought with PayPal money for at least 180 days. The current rally was obviously driven by one or very few individuals who didn't care much about the cost in USD, and why care if you buy with stolen money? It doesn't make sense to buy the market up from 0.06 to 0.09 in a few seconds, when you could buy the same amount of BTC for much less by spreading the bids over a few hours or days. There is always a robot or two which continously pushes the asks back down, along with traders who try to find a sweet spot between different asks and bids.
