I'd be happiest with one that spent only money it actually had in hand, where Election Day is also Tax Day, where only one kind of tax was permitted to be collected (property taxes, I think, as sales taxes tend to gum up the machinery of commerce and income taxes has the government involve itself in how I earn money), where religion was not the basis of law, where bureaucrats could not make law, and where the government's function was to do the things that only government can do effectively (defense, police, courts).

Since that place exists solely in my mind I would settle for one that was just like the United States but actually followed the written Constitution.
