That's a gross over-simplification of reality.
Individual elements of a flash drive will eventually wear out - they are not
infinitely over-writable.
The ultra-super-duper-cheapie crap ones average out at about 10,000 writes per
cell, meaning that's the point where the manufacturer won't guarantee much.
You may well get more on such a device in practice.
Decent drives go up to 100,000 writes before cell failures become
statistically significant

Which is why you should use wear-levelling
