It was way more than just paying the fees. The requirements were daunting. There were over 100 pages submitted, teams of security, scientists, grow experts, had to have the land/space already in place, not to mention over a million raised for GrrenLeaf of which 80% is owned by PNTV. It was extremely difficult to get that license.
As for competitors maybe in distribution but in cultivation and production of oils and waxes there won't be enough supply. The competition will come in the form of quality. As the Freak Brothers comic said in the 70s "it's better to have weed in times of no money than it is to have money in times of no weed". When NV passes recreational use in 2016 that statement will come to be true.
And as a fully reporting company, for its entire life of almost 20 years, makes a pretty good case that it is not a scam. You can see by looking at the number of PRs put out that they are not pumping.
