yeah i mean the point of Bitcoin is that it's decentralized…on a technical level that's not going to change. also another huge point is that it's natively digital which enables tons of shit. whatever, coinbase is awesome
In what way are Bitcoins "natively digital" that dollars aren't? The vast majority of USD exists only in digital form that is convertible upon request to paper and metal trinkets.
The reason some banks take so long to do transfers is not because USD is somehow analog, it's for institutional reasons that are entirely rectifiable - which is why it's not true of all banks or often, true outside the US.
