Why "Technique based"

Why "Technique based" training is not sufficient to staying in the SD Square. “Don’t assume that we are talking about one culture being better than another. Don’t believe that this mentality, of completely destroying an opponent, means that Japanese martial arts are the ‘real thing’ any more so than any other martial or combat art. Different arts address the differences in cultures and countries, circumstances and histories. There is no point in making comparisons.”  - Dave Lowry, “A Perfect Strike in the Japanese Arts (Black Belt Magazine)”

Comments: Key here is styles being a cultural creation toward manifestation of a egoistic representation of a singular application of fundamental principles toward a technique driven defense system trumps the fact, hides it behind circumstances and cultural histories both spoken and written, that all styles and systems are driven by said principles and governed by multiple defense methodologies rather than techniques.
