If we grant this for the sake of discussion, bitcoin has been capable of this for more than a decade, the masses aren't interested in this, the only thing they like about bitcoin is the fun of gambling which is the mainstream success I referred to in my previous comment.

Again, bitcoin has been capable of this since the beginning, it's a niche use case that has its place but the masses don't care, central bank money will always be superior due to its intrinsic connection to the governing authority of the region that mediates the economy - people want their stuff, they don't want bitcoin and have no reason to use it.

There's no reason for them to do so, least of all a monetary authority like a central bank. Peak bitcoin is what bitcoin looks like today.
