गणिकामकामां रुन्धतो निष्पातयतो वा व्रणविदारणेन वा रूपं उपघ्नतः सहस्रं दण्डः ॥ कZ_०२.२७.१४ ॥
gaṇikām akāmāṃ rundhato niṣpātayato vā vraṇavidāraṇena vā rūpaṃ upaghnataḥ sahasraṃ daṇḍaḥ
For confining an unwilling courtesan, expelling/throwing her out, or injuring/disfiguring her appearance by wounding/tearing, the fine is one thousand (paṇas).
Because it is both a violent crime and an economic injury that destroys livelihood and state-regulated revenue potential tied to the courtesan’s earning capacity.
