Anyway, Satoshi opnion 15 years ago doesn't matters anymore. Bitcoin is much bigger than him. It is not centralized in his old posts.
First you say that Satoshi never planned the increase of the block size. If you are shown written proof that he did plan to increase block size you simply say that Satoshi is not relevant for todays bitcoin. Seems like you just dont want a bigger block size but dont have any arguments that support it.
This makes me wonder what you intentions are that you are not willing to support a larger block size?
