The Michigan law is rather notorious.

No doubt, but even under that formulation the police will seize your car and contents and what's on your person when the crime was being committed. They won't seize the money in your checking account or take your TV just because you might have used that same car to go to work or head out to Best Buy.

So going back to the forfeiture point, very few of undocumented folks' assets are likely to be seized by the government merely because they're here in the country without authorization.

Going back even further still, it will be rather complicated legally for the feds to set up a framework that allows the Administration to get a hold of Venezuelan oil and sell it and use the proceeds for what they want without having some Congressional appropriations. I have no idea whether it's possible to do that, but it will be complicated.
