This statement is ironic because:
* Gothel is actually the one keeping Rapunzel trapped. Rapunzel is not truly safe in the tower, she is imprisoned by Gothel's selfish desire to stay young.
* Gothel's words are a lie. She does not care about Rapunzel's safety, only about her own gain.
This ironic statement highlights Gothel's manipulative and deceptive nature, contrasting the facade of love and care she projects with her true intentions.
