As one’s relevant knowledge approaches infinity, the weaknesses in an argument from incredulity/ignorance approach zero. So I don’t deny you have much relevant knowledge and I don’t think that this fallacy is as bad as most others, such as begging the question, etc. But I think your argument still fits the form, and I think that this is one fallacy smart people have to be especially careful of, as the smarter they are the more relevant knowledge they have. Also, people who can reason well are not as susceptible to totally vacuous forms of argument, so this is more important by comparison (perhaps second to the fallacy fallacy, or motivated stopping).
