There is no way you find universal consensus on the ideal block size limit. I myself believe that the limit should rise a little bit, but if to accomplish that I'll have to risk losing the aforementioned invaluable properties, then hell no. We shall improve scalability only on second layers, and if that isn't enough, then our next best course to an electronic peer-to-peer cash is a reputable altcoin like Monero, where change is more socially acceptable on a basis level.
Yup. I've got all kinds of personal beliefs regarding Bitcoin but even they evolve with changing self-perceptions and understanding. long with that, an acceptance that I don't know enough of repercussions, but trust enough that those who do, are taking this road and whichever roads in the future, that they want only the preservation of the properties that makes Bitcoin what it is today. That belief may very well change.
Mempool, fee, all this, I feel are fleeting problems (that anyway don't harm me so much yet).
