I would have problems with numbers 2, 4, & 8, and I'll explain.
First #2, it sounds like a good idea, but in all practicality it's not, heres why, alot of things Americans need & use just aren't produced enough in America to supply demand, and we all know the rules of supply & demand, the things we need that are made here, but not in sufficient quantity, would sky rocket in price.
For #4 I think it's been gone into detail enough already by other posters.
Now for #8, I think it's just a little extreme, although I do agree with the killing murders by the method of which they killed their victim. Cutting of a persons hand because they stole something is just way to extreme a punishment for the crime.
