I just wired money from my brokerage account to my checking account at a different institution. It happened in thirty minutes and I was charged no fees. Digital cash has been the bulk of cash for many, many years.
It is absolutely possible. Sweden is close to achieving it [1]. The hurdle isn't technological. People like physical cash. Consider the shitstorm that would erupt in America if the Treasury announced it would stop printing and minting physical currency.
> it's still a very interesting technological development
I agree.

Also, I've never had a wire settle in under 24 hours. It's typically 2 - 7 days depending on destination and currency.
They're probably doing an ACH [1] transfer, which is net settled [2]. They take longer but are cheaper than wires. Fedwires, once transmitted from the sending institution, take seconds to be received [3]. They're real-time gross settled [4], i.e. faster but costlier [5]; many institutions waive (i.e. eat) these fees for clients with more than ~$50,000.

[5] Why? Because they're immediate and irrevocable. The first part means the bank has to use actual funds on hand, versus hoping a countervailing transfer cancels out the work or letting a profitable (relatively speaking) investment pay out. The second part means mistakes are more resource-consuming.
It may be the leader in consumer hype of technological development, but dear deity so much of the actual daily operations seems almost third world.
Maybe they're just trying to avoid being faster than Bitcoin.
While this may be the case in some wire transfers into Coinbase/GDAX, this is certainly not the case in all cases. I've made three wire transfers of differing amount within the past three months and in each case the funds were deposited into my Coinbase account within 36 hours. Two close associates of mine have had similar experiences depositing via wire transfer in the mid- and late-December, 2017 time frame.
Granted, I have not deeply investigated all of the "my wire transfer has been pending for multiple [days/weeks/months] and still hasn't been deposited" complaints I've read on Reddit or the Coinbase forums, so it could be that I'm an unusual case vs. the norm.
A true digital cash transaction would only need communication between the two parties involved, rather than a working connection to a third entity.
