i think the value is also the ability to transfer value relatively quickly without having to sit at a bank for 30 minutes to do so.
It’s also odd not to acknowledge that banks have had electronic transfers for decades. You wait seconds for a card transaction and almost every financial institution allows you to do transfers without visiting a physical office.
AFAIK, Bitcoin takes a minimum of 10 minutes assuming that I wish to pay the going transaction fee, or as long as 3 days (or even never!!!) if I use a de minimis fee. And that's assuming a significant risk that the value of the value transferred will not have the same value by the time the transaction actually goes through.
