In “The Law” Harry mentions how he only has funds to run the Castle for 18 months… that must be his Skin Game loot. At some point Harry’s constant money problems are just ridiculous. Can our Author not just addess that?
I'm pretty sure the Author has no wish to do so.
Money is power. If Harry has access to lots of cash on a regular basis, his life gets easier, his options more extensive, it gets harder to wrap him in plot difficulties.
Remember back in
Turn Coat: Harry was hiding Morgan from the Council and almost everyone else, but he had only a handful of places he could use. Luckily for him, most of the people hunting him were used to having lots of resources and didn't fully grasp how limited Harry's options were.
Binder
did get it, and he actually said at one point "Money never gets it." Binder is working class background and he understood exactly why Harry was doing things they way he did them.
