First let's agree that we want the government to coin money and regulate its value. Then we can argue about how we want that done; I'd expect the arguments will center on how the dollar's value affects the economy.
If, by that statement, you mean that Congress should set the weight of the dollar in gold, then I agree with you. Otherwise, the government has no idea at all what the value of the dollar should be and we'd be much better off if it just stayed out of it.
Gold and silver should be the legal money with no government regulation of the ratio or value.
