How is Luigi allowed to collect money...

[cheat-master30]

In Luigi's Mansion 2? In the original, it made sense, it was technically Luigi's (future) house and the money was probably not owned by someone already, but in the sequel...

The demo begins with E Gadd sending Luigi to track down a ghost in a small house - seems that the two of them have gone into a ghostbusting business together.

Hang on... if you're in a workplace/on a contract, how the hell are they letting you take away the money you find lying around? You can barely take stuff away that you find via a metal detector and on private land, how the hell can you be allowed to go into someone's house (even if haunted) and walk off with gold coins, bank notes and solid gold bars?

I'd imagine that unless this was the agreement 'payment' method, the response to doing what Luigi is doing would probably be akin to be thrown in prison/taken to the police station.

Haunted houses seem to be the propriety of nobody, not even the country. That may be one of the reasons ghosts live here.

We don't know why is all this money in these mansions either. Nor what is King Boo's role in the game.

Luigi and E. Gadd being in a business together isn't a fact either - it's an assumption. E. Gadd may just ask Luigi services because they're friends.

How would you know if the house is owned by anyone? It is probably only occupied by the ghosts.

So, according to the demo...
E. Gadd calls Luigi and ask him if he's "ready for another task" and can get for him a particular ghost in a mansion. But it's because E. Gadd wants to study the ghost, and it seems more like Luigi is just helping him in his researches.
And the mansion seems to be the proprierty of no one.

Coins are everywhere in the Mushroom World, ripe for the taking. This is no exception.

They must have a pretty interesting economy there.

what does this have to do with the money in the mansions?

The Mushroom Kingdom doesn't have modern (highly restrictive) salvage laws. It uses standard RPG salvage law; you find it, no one is there to contest ownership, it's yours. The government doesn't even take the cut that RL governments historically have. Possibly this is an adaptation to the extreme insecurity of property in the contemporary MK.
