I've been arguing about this all night. I don't believe Satoshi wanted to "stick it to" anyone. I think he wanted to create a system that solved several problems with conventional currencies. You said that they (GS) are now in the same bus as the rest of us. I think this is a good thing because the bitcoin rules are transparent and just: the blockchain doesn't care if you're a Goldman elite or a Chinese factory worker.
I supposed you may be right, Satoshi may not have intended for bitcoin to be a libertarians wet dream, but it sure picked up a lot of steam from that movement.
Having GS move into the arena is both good and bad.
Like I said, GS brings with it a lot of lobbying power, so if some lawmakers are chomping at the bit to throw down some regulatory actions, the GS lobbyists kick down the door to their office and make it rain with $1000 bills.
On the other hand, we all know the CDO and derivative disasters that Goldman brewed prior and during the financial crisis. Keep in mind that they did this is a highly regulated market. Who knows what kind of craziness Goldman can unleash on a completely unregulated market.
