I'm guess the plan with bitcoin is to keep block size unchanged and allow fees to go through the roof, to subsidize miners. Meanwhile, users will have cheap and fast transactions on lightning network. Win/Win?
I'm sure someone has done some projections on how viable that economic model is. It would be interesting to see.
I have seen many arguments here on BCT as why this fee model does not work and none as why it will work. By the way lightning network is not a solution. Just read the Lightning Network paper
https://lightning.network/lightning-network-paper.pdf where they talk about 100 MB + blocks to make LN work. In any case I hate to say I told you so, but I sold all my Bitcoin for Monero over this issue with the bulk of the sales completed well over 3 years ago.
Edit: The reason I found out about Monero in the first place is because I was researching this issue in Bitcoin here on BCT in 2014.
