In the context of Admirals, Oda has constantly pointed out that when they are trying their DC is too much for the location to handle. This has been pointed out on MF, PH, MJ, EH.
Now whether Oda actually follows through with this or not, up to this point this has been a consistent theme with the Admirals exclusively. Look no further than Punk Hazard, and the excuse for GB and Fujitora on MJ.
It's hard not to make fun of the Yonkou when they can have a 3 day battle in their basement and everything is intact. This has been presented as an impossibility for the Admirals.
