I'm all for lightning and mints and ecash or whatever replacing traditional banking.
However I'm not convinced yet that all that tech works at scale.
I have no idea how this works out, but it seems to me that for current banks to survive they will need their own Bitcoin strategy or sell to MSTR to get on the new financial network. And maybe it's just a temporary hybrid centralized implementation of Bitcoin, but it could last long enough to make high MNAV well worth it.
