Only because
Definition
The grammar pattern "動詞ば形 / 形容詞ければ / 名詞・な形であれば + こそ" emphasizes that a specific reason is the sole or primary cause for a result. It is often used to clarify that a seemingly negative action (like strictness) stems from a positive intention. This pattern is used to express a necessary or positive justification for a particular action or situation. It implies that the reason given is the primary or sole cause of the result, and it is often used to convey a sense of necessity or inevitability.

Context
This pattern is used to emphasize that a specific reason is the sole or primary cause for a result. It is often used in formal or literary writing. It can be compared to the pattern "からこそ", which also emphasizes the reason, but is less formal. This pattern is not typically used for negative results, as it implies a necessary or positive justification.
Watch out
While both patterns emphasize the reason, 'kara koso' is less formal and literary, and is not typically used in formal writing.
This pattern implies a necessary or positive justification, and is not typically used for negative results.
The 'ba' form for nouns requires the use of the pattern "名詞 + な + 形容詞 + であれば".
Strategy
Pay attention to the context and the reason given in the sentence. Make sure to use the correct pattern and conjugation for the verb or noun. This pattern is often used in formal or literary writing, so be aware of the register and tone.
