If you use a large enough space for the number you can reduce that probability of an accidental collision to much less than that of catastrophic hardware failure at which point it isn't noticably better than having no chance of collisions.
I find the comparison unconvincing - if my hardware crashes, I know it and can decide how to recover. If two UIDs collide, my system may silently do something that may never be detected.
