Note
1) Easily confused with ~たほうがいい.
→ ~くらいなら means 'I'd rather A than B', where A is the less bad option.2) The latter clause is often the option judged worse.
→ Many sentences are used to negate/advise against B.3) Not a comparative of degree 'about'.
→ くらい here is a choice-structure, not a quantity meaning.
