Taking full RMD versus QCD

Let's say my annual RMD is $70,000. I find the following on the internet...."The tax savings from a QCD are usually superior to taking the money yourself".

If I give the $70,000 via a QCD I get zero money. I understand I will save taxes and IRMAA penalties. But if I take the RMD and no QCD, the extra taxes and penalties surely won't add up to $70,000 will they? I am in 24% tax bracket even with the RMD. I am not charitably inclined at the moment, so if I incur an extra $30,000 hit from the RMD, I am still good for $40,000. What am I missing?
