If this includes air, then the fact that air has such little mass would mean that this semblance would create PERFECT vaccums (not vacuum cleaners) all around him. That would be worse than qrow's semblance in terms of self destructiveness. Not quite; the intention was for it to be any solid object he touches, as if it were set on fire. I'll edit the post to clarify.

Also, the decay rate is based on volume, not mass; i.e. 1 cubic metre of diamond would decay at the same rate as 1 cubic metre of water (if he could affect it).
