It's exactly the same with banks, except "we" (normal plebs) cannot actually see when it happens, as compared to blockchains where all data is public. With banks it happens all the time, but no one knows, so it doesn't make the news. When it happens in blockchains (that one time), it's very obvious so it makes the news.
I'll make no argument for/against cryptocurrencies here, as the discussion if it's good/bad is futile. My comment is just a statement of fact about the differences/similarities of what we have now, and what cryptocurrencies offer.
How is it at all the same? The banking system is not immutable, the chargeback for example is available to all the "plebs" and we make regular use of it when transactions go awry.
