Argument in favour: she has met Melina, so Destiny might use his formidable debating skills to cast doubt in her mind (or she might just watch some Destiny debates and be converted to Destiny-style progressivism). Another argument in favour: according to the libertarian economist Tyler Cowen, libertarianism is essentially on life-support and many libertarians have moved on to "less savory" positions. (Although I wonder if this is just due to seeing the world through the lens of the outdated political spectrum, and maybe if he got with the program and saw the world through the lens of the political compass like all right-thinking people should, he'd realise those libertarians hadn't necessarily moved on.)
