Maybe I do not understand what you mean by meaningless? Beliefs can have consequences that do not depend on the cause of the belief. The actions one takes depend on one's beliefs more directly than they do ones reasons for those beliefs, in many cases. (For the insect+food example, consider the options of taking it as axiomatic on a whim, or being made to believe it via propaganda+magic(magic here just for sake of argument). What causes the person to believe the thing does not effect whether the person intends to allow a fly to land on their food.) (If I believe my hand is on fire, whether I attempt to remedy this does not depend on whether I see it or feel it, nor on whether it is on fire. If I attempt to remedy it, while it is not on fire, there may be an unpleasant result. The truth does of course matter, but beliefs are a useful predictor of future actions.)
