Is "a supreme force" the kind of thing you can add up like troop movements? A main point of the original argument is that the supreme forces claimed are mutually exclusive, whereas troop counts are not.

If the counter-claim is to be as vague as, "There is something real about spirituality," we can all agree on some level. Some people will go with the level of common problems in human psychology that lead to the delusion of spirituality. Others will go with the existence of a supreme being. Taking these points together and adding them up to "something real" is not solid conceptualization. (Similar problems with adding together the belief in a supreme being and those who explicitly believe in a non-personal supreme force.)

Alternate approach: taking the Simulation Hypothesis seriously means having a significant prior for the existence of some kind of creator. I doubt that theists or people accepting the Simulation Hypothesis would say that their beliefs mostly overlap on the important points.
