Yeah, have you ever tried to send .002 gram of gold to anyone recently?
Leave your comfortable bubble and look at countries with hyperinflation like Zimbabwe/Argentina, how are they going to use a cash (not dollar) in a trustless fashion?
If you think that crypto's hardier than real world fungible assets when the shit hits the fan, I imagine it's not me who is trapped in a 'comfortable bubble' as you so condescendingly put it.
Given now infamous recent disclosures about fundamental flaws in our trust in IT at the deepest levels we can imagine, I suspect you vastly overestimate the resilience of digital 'securities'.
Never mind power cuts or flat batteries...
