The US won't prohibit anyone from traveling there. In fact, it can become a problem when people insist on going to dangerous places. That 85 year old guy who went there and was detained for a while became a US government problem.

Korea, Democratic People's Republic of
November 19, 2013
The Department of State recommends against all travel by U.S. citizens to North Korea (Democratic People's Republic of Korea, or DPRK). This replaces the Travel Warning for North Korea of October 1, to update information on the risk of arbitrary arrest and detention of U.S. citizens in North Korea.
Travel by U.S. citizens to North Korea is not routine, and U.S. citizens crossing into North Korea, even accidentally, have been subject to arbitrary arrest and long-term detention. Since January 2009, four U.S. citizens have been arrested for entering North Korea illegally, and two U.S. citizens who entered on valid DPRK visas were arrested inside North Korea on other charges. The Department of State has also received reports of DPRK authorities arbitrarily detaining U.S. citizens and not allowing them to depart the country.
The Government of North Korea has not only imposed heavy fines on, but has also detained, arrested, and imprisoned persons who violated DPRK laws, such as entering the country illegally or attempting to contact private DPRK citizens without government authorization. Travelers to North Korea must enter the DPRK with a valid passport and valid DPRK visa. Foreign visitors to North Korea may be arrested, detained, or expelled for activities that would not be considered criminal outside North Korea, including involvement in unsanctioned religious and/or political activities (whether those activities took place inside or outside North Korea), unauthorized travel, or unauthorized interaction with the local population.
North Korean security personnel may regard as espionage unauthorized or unescorted travel inside North Korea and unauthorized attempts to speak directly to North Korean citizens. North Korean authorities may fine or arrest travelers for exchanging currency with an unauthorized vendor, for taking unauthorized photographs, or for shopping at stores not designated for foreigners. It is a criminal act in North Korea to show disrespect to the country's former leaders, Kim Jong Il and Kim Il Sung, or to the current leader, Kim Jong Un.
If DPRK authorities permit you to keep your cell phone upon entry into the country, please keep in mind that you have no right to privacy in North Korea and should assume your communications are monitored. It is a criminal act to bring printed or electronic media criticizing the DPRK government into the country. If you bring electronic media, including USB drives, CD-ROMs, DVDs, or laptops, into the country, you must assume that North Korean authorities will review the information on those devices. Please be sure that the information contained on those devices does not violate the laws or regulations of the DPRK, as penalties for knowingly or unknowingly violating North Korea's laws are much harsher than U.S. penalties for similar offenses. Sentences for crimes can include years of detention in hard labor camps or death.
Since the United States does not maintain diplomatic or consular relations with the DPRK, the U.S. government has no means to provide normal consular services to U.S. citizens in North Korea. The Embassy of Sweden, the U.S. Protecting Power in the DPRK capital of Pyongyang, provides limited consular services to U.S. citizens traveling in North Korea who are ill, injured, arrested, or who have died while there. The U.S.-DPRK Interim Consular Agreement provides that North Korea will notify the Embassy of Sweden within four days of an arrest or detention of a U.S. citizen and will allow consular visits by the Swedish Embassy within two days after a request is made. However, the DPRK government routinely delays or denies consular access.
U.S. citizens who plan to travel to North Korea are strongly encouraged to contact the U.S. Embassy in Beijing, China, about their trip by enrolling in the State Department's Smart Traveler Enrollment Program. If you enroll in this program, the State Department can keep you up to date with important safety and security announcements via email messages (though you may not have access to email while in the DPRK). Enrollment also makes it easier for friends and family to get in touch with you in an emergency via the U.S. Embassy...
U. S. Embassy Beijing:The Embassy is located next to the Ladies' Street (Nuren Jie) and Laitai Flower Market, near the Kempinski Hotel and Lufthansa shopping Center on Tianze Road near the Liangmaqiao subway stop.
