It isn't a matter of forcing people to pay taxes, and the fact that so many people in this thread keep going back to the same point is a frightening prospect to me. The US has plenty of our own issues with addressing social issues, but I'd rather the entire country implode due to social issues rather than the government forcibly controlling everyone's purchases and tracking their every movement for the greater good of society.

Americans hate laws like this in the US because we've already sacrificed liberties for security with things like The Patriot Act, and all it got us was our own government spying on it's citizens communication. Expanding the scope of how the government is allowed to forcibly direct or interfere in your life is generally a bad idea, even if the people you support politically make it look sexy and cool.
