I think the point is that the even horizon of these black holes would be smaller than a proton. Hence, electromagnetism would be a stronger force at this scale than gravity and the probability of such a black hole even coming close to an matter would be vanishingly small. And if it did, it wouldn't make any difference since theblack hole would decay faster than it could accumulate mass.
even horizon = event horizon. oops. Bloack hole got the 't'.

perhaps the principle of the chain reaction can be applied here: create black holes fast enough for the process to become self sustaining.
