It's not really "no hardness" as much as it is "hardness (i.e. damage resistance) set by the DM as appropriate for the situation." So a DM is well within his/her rights to say that you cannot, in fact, make a hole in an Adamantine wall with a quarterstaff, whatever your Str bonus is. A DM can do this anyway, but it's nice to see it spelled out plainly.
