If there was tzaraas today, some enterprising young investor would open up full-on חוץ למחנה resorts. Private villas, jacuzzis, cold plunges, and 5 star cohen service (for an added fee). Not to forget a menu featuring Crème brûlée, Stuffed Choux Puffs, Pistachio Cannoli and much much more!!
[I would say places this investor would probably come from but that might be לשון הרע or at least אבק לשון הרע necessitating my own foray מחוץ למחנה].
