Also, the average tx size is smaller with SegWit.
well those who say we need block size increase say we do not need SegWit so the average tx size is 450 bytes. and with SegWit we are getting a capacity increase (on chain scaling). I would agree that it is not enough. but I also say the way to go is not to increase the block size as BCH did.
Thank you for a good discussion. Obviously, I am a living example of a person saying that we need to eventually increase the block size
and work on more efficient ways to store and execute transactions (SegWit is just a one example here)

I simply think that bitcoin as a technology cannot get frozen. It must develop and adapt as the technology available around it changes constantly. In our constantly changing world, stagnation is death.
