> Coffee shops don't accept gold bars either, yet gold has certainly been money (not so much these days).

This is true but it's largely because of the logistics. It's not that coffee shops don't want gold, it's just that it's too inconvenient to accept it. Bitcoin, on the other hand, is incredibly easy to accept. And unlike gold, Bitcoin can't be counterfeited. I know, in the USA at least, "digital gold" is the current narrative. But "daily currency" is just around the corner.
