I do not see that core's has any tenable objection to 2X.

[1] Tech has moved on, 2mb is not that big, HD space and bandwidth are much cheaper
[2] BCH has proved you can go bigger blocks and have significant value network, and BCH network has not collapsed.
[3] It provides choice as to on chain or of chain transactions
[4] there is no such thing as spam in the network, but I will use the word "spam" as shorthand for transactions person A does not like.
[5] If you say go 8 times the blocksize and 1/2 the price for fees it will be 4 times more costly to "spam" a block while providing much lower fees. Given there are limited bitcoins, the spammer will run out of BTC to spam.

I welcome any discussion as why I am in error, but as it stand to not 2x then a few years later 4x and so on, seem in bad faith by core. It forces the question cui bono?
