The articles and the prayerbook don't speak for themselves, just as Scripture doesn't. Everything exists in a web of meaning and context and tradition. According to the written words, episcopacy is necessary, and according to the lived and known tradition as recorded for hundreds of years from that point to today, no non-episcopal ordinations were accepted as valid. If you are episcopally ordained today, you may try to transfer your orders into an Anglican jurisdiction. If you aren't, you simply may not. Take that for what you will. I wholly agree. What you'd written supports my point entirely: the necessity of specific requirements in the administration and the rites of the Church. On this the divines, @Philip Barrington, and @Stalwart agree. However it is at odds with what you said originally, wherein the specific requirements were made to seem optional, and even, dispensable, since "it is all up to God anyway." It seems we have rejected this fideism now, together, for which I'm glad. Truce?
