The current tax regulations actually put Australia at a disadvantage to the rest of the world. If they change these regulations now, a lot of businesses will return, and it would boost their economy. When anti-money laundering and counter-terrorism financing regulations are applied to Bitcoin exchanges, it would stimulate a growth in that area of the world, like we have never seen before.
Ripple will definitely get a foot hold, when the banks accept it as the default currency and the technology to invest in the future. In it's very nature, it's everything that Bitcoin does not want to be. We need the freedom to have full control and some anonymity. The centralized nature of these regulated exchanges are a mayor risk factor <MtGox> and a source for government monitoring over financial matters of private citizens.
We already had all that with VISA & Mastercard & PayPal and we decided to use Bitcoin, because it offered us a different way to control our own money.
