What it means
くらいなら expresses a strong preference for one option over another, meaning “rather than” or “if the alternative is X.” The preceding verb usually appears in the dictionary form, and the following clause presents the speaker’s preferred action or outcome. It often conveys that the action before くらいなら is especially undesirable, extreme, or unacceptable. The construction itself does not change for politeness; politeness is shown in the following main clause.
Usage note
In this meaning, くらいなら normally follows a verb in the dictionary form, as in V-るくらいなら. Do not confuse it with くらいなら meaning “if it is only about...” or “as much as...,” which belongs to a different construction.
