I think a lot of rewrites happen because new people come along and they are not interested in reading and learning existing code. They just want to write new code and in their mind "the way I do it is better". A prime example is the Javascript ecosystem with such a high churn rate it caused a new kind of burnout: Javascript fatigue. Programmers seem to forget when you throw away code, you're not just throwing away text, you are throwing away years of accrued knowledge.
