This sort of thing apt to put a hodlers mind at ease.

There definitely is something to it. But it depends on adoption whether or not this scenario will come to pass. I think Bitcoin is best suited to complement precious metals to some extent as a store of value for the digital age rather than become an every day currency. With sufficient adoption, I can imagine Bitcoin being included in a basket of commodities and foreign currencies making up reserves in central banks. Initially, it's share might be very small but with maturity and decreasing volatility it may rise in importance. The US dollar is the world's reserve currency of choice at the moment but that is bound to change with the share of the US economy of the world's economy gradually becoming smaller each year.
