Segwit is not about saving space for plain full noes, the space is already saved in Core (if the user chooses to save it). As you note, local space savings can be done purely locally. Segwit increases flexibility; fixes design flaws; saves space for nodes acting as SPV servers; and saves _bandwidth_; and none of these be done as purely local changes.
Again I apologize for not being smart enough to instantly understand all the changes segwit does and I was misled by errant internet posts that segwit saved HDD space for the blockchain.
thank you for clarifying that it wont save space for full nodes.
Also, my understanding now is that iguana can just treat the segwit tx as standard p2sh and with the caveat that until it fully processes the witness data, it would just need to trust that any such tx that are mined are valid.
I would debate with you on many claims you make that I dont agree with, but I see no point to debate with words. I will make an iguana release that will demonstrate my claims. Fair enough?

The problem is that what you lost a lot of credibility by making your claims earlier and now it'll be hard to take your software seriously. Basically, you are asking us to check out your rocket after you argued against the laws of gravity.
