This is obvious to me, that no state will have the pool of players that will be big enough to support OLP, let alone multiple sites. California would have the best shot at going it alone, but we still have silly moralists in charge.
The current state of affairs is such that the US can barely support the 3 or 4 public options we have. Overall game selection is less than what we want IMHO.
Subscription sites may or may not be thriving, I really have no clue. Hard to imagine that the economic model the WSOP uses is failing. That would go to ZEN as well, where they make most of their bucks from in game advertising, but it might be less profitable than I imagine.
All this adds up to a potent argument for deposit taxation at local (address dependent) rates, as if we were buying a Big Gulp. Revenues for each State, or country, will vary according to their local taxes.
I just haven't figured out how to deal with Freerolls. They, as always, are a great promo tool, and will not go away. It could be that freerolls could be taxed at 10% and that 10% would go to the Fed for the services they render, like providing regulations for fair and accurate (poker) banking and RNG audits.
