I ran a Corolla with a holed sump, and no measurable oil. I was going to scrap it.

After 3 months it was going ok so took it to a mechanic. They repaired it, said ‘don’t do that’ and it carried on for another 5 years before I sold it.

At some point, even a Corolla will need a repair or maintenance significantly more expensive than the remaining value offered by the old car. It sounds like if you drove it for 3 months without oil, you didn't have a lot of options at the time or you might have put oil in your car in the meantime?
