Pattern: [ば-form] + こそ（sentence often ends のだ）
愛していればこそ、厳しく叱るのだ。

= I tell you to stop drinking precisely because I worry about your health.

Signature usage: justifying tough love. The listener sees strictness; ばこそ reveals the caring reason behind it.
てこそ vs ばこそ:
・てこそ = "only by DOING X" → condition for a good outcome
