I'm not sure I understand what your point or objection is. Is the problem that the people who organize PM tournaments in your area don't run Smash 4 events too?
I agree that the question being asked is somewhat vague. I think you might have got it though haha.
Basically, there has been a pretty rough post-Melee divide between Smashers. Because Melee is quite technical and perceived to be harder, along with PM, both games can be seen as more fun because with more techniques you have more to do, the game is more difficult to master, and seems less simple. That's not to say Smash 4 isn't complex, but because of some similarities it has to Brawl (which again, isn't exactly simple, but has less options, and more of a hit-and-run playstyle which people find less interesting it's taken less seriously, which while unfair and bias gives the TOs the freedom of choice in what they are willing to run. It's also a little bit of a popularity contest--it seems like Melee and PM are being played more in your (The OP's) area, and so obviously more people will play and TO it.
To get people interested in Smash 4, see if anyone is interested in it by interacting with them physically at tournaments, and gauge their responses in regards to participation of a hypothetical Smash 4 tournament. You can also find people outside of the group mentioned, with Smashboards being a lovely way to do so. By getting more people interested and involved in your group, you can create demand for a Smash 4 scene, which can make a tournament more likely.

says it best with the statement "If you want there to be Smash 4 tournaments in your area, they should be run by the people who are interested in Smash 4 tournaments. Perhaps that person is you," an entirely true and plausible statement. Because it seems like your community is barely burgeoning with a Smash 4 community, you should try to make strides like the ones mentioned in both our posts, as well as other things like perhaps finding a different venue, finding ways to get people interested in this game, and other things you can think of. Once again, the boards can serve as an excellent sounding board for this (which clearly you know haha).
In either case, best of luck trying to build a scene, ignore the haters
