bitcoin has never failed, the blockchain has always been working, nodes are up and running and spread across the globe, no exchange has ever suspended bitcoin wallet to investigate!
you seem to forget the 2013 Berkeley->leveldb event involving the issues with the locks. that caused alot of drama, including a period of time exchanges halted deposits/withdrawals to avoid issues until the drama was over.
there is no point pretending something is perfect utopia and preaching utopia to the already converted. what is best is to accept there have been issues and there are issues and to learn from them and to fix them.
EG
some state that core is perfect and has no issues.. if this were true there would be no need for segwit or schnorr or increasing blocksizes or other things.
