2006 Mint Regulation concerning nickels and cents

I found a mint regulation that prevents the melting of nickels and cents.

Published in December 2006, I have taken the liberty of quoting their news release here.

Specifically, the new regulations prohibit, with certain exceptions, the melting or treatment of all one-cent and 5-cent coins. The regulations also prohibit the unlicensed exportation of these coins, except that travelers may take up to $5 in these coins out of the country, and individuals may ship up to $100 in these coins out of the country in any one shipment for legitimate coinage and numismatic purposes. In all essential respects, these regulations are patterned after the Department of the Treasury's regulations prohibiting the exportation, melting, or treatment of silver coins between 1967 and 1969, and the regulations prohibiting the exportation, melting, or treatment of one-cent coins between 1974 and 1978.

The new regulations authorize a fine of not more than $10,000, or imprisonment of not more than five years, or both, against a person who knowingly violates the regulations. In addition, by law, any coins exported, melted, or treated in violation of the regulation shall be forfeited to the United States Government.

Now, I don't travel overseas very often but I wonder why I shouldn't be able to take $6.00 worth of nickels with me?
