At first, I can see where you are coming from by mentioning the prolonged elitism in these forums, but I think that you are confusing that term for 'competetive' players, and categorizing them as elitist because we have the same objectives.
Many of us here at smashboards try to provide a safe haven for competetive players who share our interest. We freely discuss the games techniques and how we can play with the wide plethora of characters at our disposal. In addition to that, we participate in tournaments and host them internationally. You can say that this is the best place for a smasher to tap into his abilities beyond the basic game, and make a name for themselves.
Now, with these things in mind, how can you be astonished that a more dedicated player can easily beat a player who doesn't dedicate himself to this game? Should the game be watered down to the point that it lacks any diverse mechanics? Even this game appeals to a wide audience, a skill gap will always exist as long as their is the chance that tactics can be etsablished in a algorithmic form.
I think that it's very egotistical of you to label us as 'elitist' when we are simply playing the game in a manner that benifits our community. Unfortunatly for you, we aren't going to cator towards casual people because they refuse to practice and become skilled at the game. You can't expect to achieve the same amount of success as a person who has dedicated himself without putting in aformentioned effort.
Skill gaps will continue to exist as long as those who refuse to learn complain. But, like most casual players, you feel that derailing the competetive playing scene will make the gap closer, when in reality you are refusing to coexist with your superiors, and make the factors for winning difficult to determin by adding unecessary variables. Even if we did obey casual rules, the majority of the wins would go towards the competitives? Why? Not because of the technical aspects, but through experience and knowledge.
Many casual players though that the removal of two essential melee techniques (Wavedashing & L-canceling) would derail the competitive community, but it didn't. Many melee veteran players are still showing great success in Brawl tournaments despite the game being new/less technical.
No matter which way you slice it, competitive players aren't just elitist, but they are over all better than the average player at the game, techniques or not. The technical aspect of smash may have been extremely important in Melee, but knowing how to use the fundimental mechanics was just as important. This will not change in Brawl. I guarantee it.
