> Blockchain requires distribution for trustless implementation though, which is the duplicated expense
Trust scales with something like Metcalfe's Law. E.g. a consortium of ten independent banks is probably 99% less likely to steal my money than just Wells Fargo. The idea that we need millions of independent entities to get substantially better security than the status quo is just propaganda that gets spread by Bitcoin maximalists.
There is a cost of duplication, but at the level of duplication you actually need the cost isn't that much compared to the benefit.
