In this case, I don't think we even reach that question. When Greenspan's business did not obtain the appropriate license, it left the money transmission business, making it hard for me to understand how the remaining money transmission businesses (assuming that they actually are money transmitters) are his competition.

Maybe not presently, but my takeaway is that he accuses his would-be competition (and those funding them) of not following the law. I am not familiar with the law enough to know whether you can play the well-they-don't-have-to card.

But my question still stands, is there any recourse for a company who believes it is held to a double standard with regards to direct competitors?

I believe such a company could sue for unfair competition in California (but talk to an actual lawyer before acting on this belief--I am not a lawyer). The key is that it has to have actually been injured by the action of the competitors.

They might be able to seek a writ of mandamus compelling the appropriate authority to enforce the law.
