With charities you can always make your own. Don't have that option in your system.
I'm not American, but aren't some taxes that go to education/welfare/healthcare on a federal level? If so, are you going to tell people to leave the country? It's very expensive and for many practically impossible.
Besides, is the goal not here to spend the money as efficiently as possible? In that case we need as much competition and experimentation as possible. Something I think is achieved to a much higher degree with my system than yours.
Also, your suggestion still doesn't make it voluntary. In my system someone can not donate to charity, but use their money for something else. Charities are not the only way to help the worse off.
