Transaction will volume ebb and flow significantly. Some people have been looking at transaction volume charts over time and all they can see is an exponential curve which they think will go on forever, yet nothing goes up forever and it will go through significant trend cycles (like everything does). If you dont want to hurt the fee market, the blocksize has to be elastic and allow contraction as well as expansion.
