Ah, but the trick is to get the low tolerance ones. Two reasons: A) then it’s +/- 20%, right? Which means you bucket them and resell the + ones, using the rest to mine crypto, and B) you save money because 5% of 0 is no more than 20%.

It's also physically impossible for it to actually be 0 ohms. Unless there are consumer grade superconductors that I didn't know about.
