i generally favour optimisim, however it seems like the more likely best-case outcome for Bitcoin is that the world gets to operate on a sound money standard, albeit that the average Joe will interact with the asset through some semi-to-non custodial mechanism. 

all 8 billion people being able to participate, without permission, is a definite win. as too is the lack of friction, across borders. 

a small minority no longer being able to self finance, by way of currency debasement, is also a wonderful victory.

self custody for all should remain firmly within our sights, however if only the aspects above come to pass, the battle will still have been worth it. by a large margin.
