I don't think that's an accurate summary. The author's own summary (last three slides) doesn't mention volatility.

Crypto enthusiasts like the lack of centralization on supposed ethical grounds, but the author draws a separation between ethical considerations and considerations of effectiveness. The author makes the point that fiat is effective.
