For practical purposes it is achievable to ship working software. Plenty of people do it.
I’ve used Safari, Notes, Reminders, and Calendar daily for years and have never encountered a bug. Same with my time tracking and invoice software. Maybe there are bugs but I have been able to go years without encountering them. I have also never knowingly shipped a bug for my service https://sumi.news, and have fixed every bug brought to my attention. There are zero bugs in my bug tracker, and when they are reported they are fixed.
If you’re discovering more bugs than you can fix, and you always have a long list of bugs, that implies something wrong with how you design, implement, and test software, and an engineering team that is incapable (for whatever reason) of producing working software.
Tolerating defects is little more than apathy and a lack of quality standards and craftsmanship.
