>> maybe disintegrating a bunch of them isn't a showstopper
But it isn't about destroying a bunch of them. Cut corners on checks and you very quickly blow up all of them. Any slight increase in the failure rate of individual parts, saving a few pennies, multiplies exponentially across the entire rocket into total system failure. So the money-saving approach is actually to test test and retest, to cram down the failure rates so low that the cumulative rate become acceptable (about 1%).
