Not only is it not working, but the government's war on drugs only wastes taxpayers' money. And more importantly, using drugs on one's own body is not a real crime. Imagine how much safer we'd be if only a fraction of the money used on the drug war were used to defend against real crime. Businesses and farms must operate without tax funding. People are better off with free trade than tariffs.
Taxation is theft.
In short, if you don't want a service then you shouldn't be forced to pay for it. Let's replace taxation with voluntary services or user fees. For example, our current tax-funded court system could be maintained entirely by user fees. Perhaps a zero-tax America will take years to achieve, or perhaps it can never be realized at all, but that doesn't mean we shouldn't aim for the highest ideal of a completely noncoercive government. Individuals should not be taxed to pay for foreign aid, corporate interests, or social welfare.
