The only security against nation states with hundreds of billions of $ at their disposal is either through obscurity (monero) or through ubiquity (too big and important to attack).
Practically, it seems a compromise to 2MB would buy time to develop and roll out other solutions (segwit, LN, SC, etc) and could allow us to have more productive dialog in the interim.
Have we considered the fact that a lot of those small-blockers seem to also have a vested interest in the success of a certain altcoin?
Meh, I don't dismiss their concerns completely because of this.
There are real concerns about maliciously formed 8MB blocks made by a dominant selfish miner. IMO it would be a miner acting against their interest in continued income, but the possibility is there, and the worry is not completely unfounded.
It's greatly diminished at 2MB, so I think that's a good compromise to buy some time and allow us to stop obsessing and fighting for a while.
I have to admit the King Satoshi and his little castle analogy made a lot of sense.
Is there any indication anywhere that Satoshi was aware of difficulties with scaling for mass adoption?

Besides, 10 minutes is too long to verify that payment is good. It needs to be as fast as swiping a credit card is today.
