All the force and stress happens when the rod pushes down on the crank after combustion to turn it. Also some force when the crank pushes the rod back up. The nuts are there when the crank has to pull the rod down (the intake stroke for example), I don't think theres much force or stress acting on the nuts or studs coming from the stock rods. When the nut got loose, it would've had the same effect as throwing a rod bearing, there would be some slack and some slapping around. The only difference is the slack causes way too much stress on the stud (and maybe the nut). So while you could get away with driving with a thrown rod bearing for a while, the moment the nut got loose it would've broken the rod end cap off very quickly. That's my guess.
