Nonsense.
Block size limitation was not in the initial white paper or BTC implementation. It was introduced as an anti-DDOS measure later, and was always meant to be increased when necessary.
SegWit also was not part of the original BTC, but a fairly recent hack and a temporary measure with questionable benefits.
While Bitcoin did have a scaling plan from the beginning (bigger blocks), technology cannot keep up with Bitcoin's growth.
You'll see it in a year when Bitcoin Cash will have half or less as many nodes as it does to day, QFR this.
I don't know what your point is, other than being condescending (seems to be a popular way to treat new people on this forum).
SegWit was not mentioned in the white paper since it is a fairly recent development (2015 I believe). There have been rather serious security concerns raised about it recently, and it doesn't increase block size much (1.6x?).
I never mentioned Bitcoin Cash, which is not even the topic of the discussion?
