I'm sorry, but I feel that the PPA has already lost the fight and it does not matter what any of us peons do anymore. They lost it when the players didn't get their money back after Poker stars and FTP were closed down. The fact that they didn't indicates that those two companies didn't have the minimum cash reserves that they should have maintained. It would seem to indicate that that internet poker wasn't the ethical business that they promoted and the Federal Govt. was "right" in what they did to close them down.
To me, it is really hard to justify legalizing, even in a regulated way. The govt. passes laws against particular behavior all the time. It regulates where necessary to keep business's running ethically where self regulation hasn't worked. Regardless, there will always be unethical business and unethical people striving to bypass whatever rules exist. How does one guaranty to the public that they will never be shafted again?
If you want the Govt. to change its collective mind, then the industry needs to correct the injustices of the past to help indicate that they can be ethical in the future. It can't just be about promotion and getting enough people and legislators in your corner so that they can pass legislation legalizing it. There has to be more...
As a gambler, suppose someone ripped you off. Would you just blindly repeat the process or would you require some form of guaranty before gambling with them again? Would you not require, to start with and as a minimum that you would be compensated for the previous ripoff? In addition add some form of external guarantee that such a ripoff could not be repeated? In the current state of affairs, as far as I can tell, none of that is happening. So I can't see how anything done by the PPA matters.
Just my 2 cents
