What would ensue if gov't seized nt funds w/o plans of returning them?

[geormiet]

Lets say the feds announce they have confiscated all american neteller money,and they say that since the money was used for gambling, which is "illegal", that the money no longer belongs to the customers. (or some other validation fro keeping the money)

What would you do personally? What do you think would occur on a national level?
