NEW YORK (CNN/Money) - America's wealth is the envy of much of the world. But there are things that money can't buy here -- and we don't mean love.

The United States bans the import many products enjoyed in other countries. When it comes to food, in particular, the federal government can be pretty picky.

Sometimes, bans are intended to keep out some pathogen deadly to plants or people. Other prohibitions are designed to protect an industry. Still others are attempts to bolster endangered species.

Whatever the reason, though, there will always be Americans who look to circumvent the laws. In many cases, the government will raise little objection. Nevertheless, there are practical, legal, and moral issues with many of these bans.

Still, it's nice to imagine a time Americans might be able to buy everything from cigars to cheese without fear of sanction. When that day will arrive, however, may be more difficult to picture.
