My comments weren't about who's entitled to what. I'm personally less concerned with my own rank, and reduced the number of ranks (and amount of hierarchy) in my curriculum. I'm not full-time, so I doubt I'd ever be on par with the creator of NGA, nor will I ever put in the level of effort that Richard Bowe did (the one who brought it to the US, and became de facto head of style). But I'd be opposed to the concept of reserving rank for either of them, because it assumes nobody will ever reach that level. I know others who could potentially have passed Bowe's peak skill level (I didn't know him in his peak years), and nobody except Bowe can speak to what Morita's skill level was. And there are others who have arguably made contributions to the art equivalent to each of them (not the same level of accomplishment as the early Gracies, mind you). It's a conceptual objection, mostly. Certainly, every group is entitled to determine these things for themselves.No one is entitled to anything. There are some things to which you are not entitled. Who really cares? There is a rank that is unattainable and reserved for the founders of the art. It's their art, and their rule to make or not make. Provided their motivation isn't illegal, there is no entitlement here.
Regarding whether the founders are superior to you, chances are, they are. Not because you are a bad guy and they were perfect. They may have been deeply flawed human beings. But there are a gazillion different measures of a human being. They had the combination of skill, resources, timing and gumption to start a martial art style and make it stick. In this case, BJJ continues to grow world wide. I was just at a tournament this weekend where there were close to 1,000 individual competitors, somewhere in the area of 10,000 matches. About 400 were kids. And this is a regional tournament the week before the Pan Ams in California (in other words, this is usually the least attended tournament of the year). The tournament has grown over the years to a two day event with 8 mats running continuously for about 18 hours.
And that's even before you get into whether they are more skilled in the art than you, which they probably are. Generally, guys who start their own martial art that is successful bring to the table martial experience that will be diluted over time.
To be clear, it's a retrospective determination. I mean, lots of guys try to start a new martial arts style and fail. You are probably superior to those guys, and may mock them relentlessly for their folly.
