Zero bugs sounds neither practical nor necessarily desirable. I still remember to have been quite happy about the first bug report I received -- only then I knew that the software was actually being used and didn't vanish in someone's vault. Time to market is still a thing and incompatible with overzealous bug fixing. I would settle on a zero-regression policy. Then at least you keep happy customers happy and potentially reach fewer bugs in the future. Of course it depends on the application. An automotive ABS system has different requirements then an IRC server.
