There have been a number of people over the years who have started with a relatively shallow exposure to existing systems and through dint of lots of hard work, study, and testing ideas ended up creating solid martial arts which have withstood the tests of time.
There have been a much larger number who have started with a relatively shallow exposure to existing systems and have constructed crappy new arts which lack depth, have no unifying principles, and don't add much of anything to the martial landscape. These usually fade away in a short time unless the founder is an exceptional self-promoter.
The advantage of "credentials" (ranks, teaching certificates, etc) is that they can give an outsider some assurance of what they might be getting with a particular instructor. If I know that Joe Blow is a badass master of full-contact bare-knuckle striking and he issues a teaching certificate in his art to Joe Schmoe, then I can figure there's a good chance that Mr. Schmoe may be able to offer me some good tips on striking methods. If I'm looking at an instructor who has no such credentials (or if I know nothing about the person issuing their credentials), then I won't know much about their skill or knowledge until I have a chance to see them move or interact with them in person.

Do you have a link to your YouTube channel?
I don't teach complete styles. I just teach techniques.
Yea around that area. I can give you a free lesson if you're interested.
Here is the sort of thing, more so than your lack of paper credentials, that makes me skeptical of what you have to offer...
"
I just teach techniques"
Techniques are ... not unimportant, but certainly less important than tactical concepts, physical principles, training methods, and approaches to attribute development. Any good martial art is much more than a collection of techniques.

The person you are talking to in that comment has been training in the martial arts more than 4 times longer than you have. Maybe you have something useful to show him. Maybe you don't. Either way, if you have the drive to learn and grow that I would expect from the creator of a new system then I would expect you to be more interested in what you might learn from him rather than the other way around.
