I see one or two ways to work around that. She can either be rich enough to finance the crime organisation she'll be a part of. Or, what I had in mind, since she's still young she doesn't actually have control of the companies which are being managed for her. She have access to a certain % of it? 

Either way, I am not a power player and I didn't think of using it all that much. Mostly, it was some reason to have a big House and to explain how she got her suit made.
