it was for fellow forumite BurtW - well, actually for his daughter.
Fair enough, yes you were merely trying to help him as well.
1) You said "the increase is very small", correct? Accordingly, I interpreted this as you agreeing there was indeed an increase. In what way is that misrepresenting your statement? I am just trying to cut through the fog to figure out exactly _where_ our disagreements actually lie, in this thread full of shillery on both sides of the argument. Do you now deny there is an increase in bandwidth and storage required with vs. without The SegWit Omnibus Changeset for representation of each transaction? And if you do, then by what mechanism are the main chain transaction structures correlated to the witness chain transaction structures?
Segwit is a necessary for Schnorr signatures which do indeed reduce Bandwidth and storage(far more than what is added with segwit). Additionally, there are greater concerns than storage costs and bandwidth for scalability such as eliminating the quadratic cost in transaction signature hashing and reducing UTXO bloat.
Are you trying to insinuate that the package of benefits that Segwit provides is worse than the initial slight increase in overhead to bandwidth and storage costs?
