People suggesting be your own bank with bitcoin forget that a bank is more than just a place to deposit money, its a place to get loans and access other forms of financial activity that bitcoin cannot or at least does not currently do.
True, and right now Ethereum and Ripple are performing a mating dance with commercial banks in order to capture that (very inefficient) side of the equation. What I'm saying is that I think private persons and smaller companies can trust Bitcoin with their life savings, and then they can use other technologies that are lower trust for other use cases. They might have a "current account" where they use Monero for daily purchases, for example.
Ethereum/Ripple/Dogecoin/etc. are not places where I would imagine many sane people will park their most precious reserve capital.
