Isn't inflation only really bad for people who have long term, non-inflation adjusted fixed income? Otherwise, it seems like real interest matter more than inflation. If inflation is 10% but CDs are paying 13% wouldn't that be a good thing for most investors? They'd have a 3% real yield for a change.
First, it is unlikely your CD will be yielding 13% if inflation is at 10%. If inflation ramps up quickly, a lot of money will be tied up in lower rate terms AND rate increases will lag inflation. This was the case in countries that went from "inflation" to hyper-inflation.

Secondly, even without hyper-inflation, you also need to account for taxes on phantom gains. If the magical CD yielded 12% and inflation was 10%, your CD return after taxes (assuming a 25% combined Fed+State) would be 9%...and you would be losing purchasing power.
