<p>It's perfectly valid (even good) to explain that a question is a special case of a more general phenomenon and then address the general case. It's also fine to explain a concept in a different domain and then explain the connection with the topic of the original question. But I don't think your answer is a good example of either of these, and the intuition you claim it offers is not evident. The question is about linear regression and OLS. You bring up logistic regression, perfect separation, MLE, and overfitting, but don't make much of an attempt to explain why invoking these concepts is useful to address the original question.</p>
<p>Note I have not seen your answer before this and so was not involved in the decision, but would probably also have voted to delete.</p>
