At least 8.5 million won needed to remove graffiti from Gwanghwamun... Can we demand this from the perpetrators? (South Korea)

It was estimated that it cost nearly 10 million won (approximately 1,069,000 yen) to remove graffiti from Gwanghwamun Gate in Seoul.
According to the National Heritage Administration and other sources on the 24th, the Gyeongbokgung Palace Management Office received at least 8,000 yen in damages on the 11th for the cost of removing graffiti from the stone walls of Gwanghwamun.
The provisional calculation shows that 500,000 won (approximately 8,000 US dollars) was spent, taking into account the cost of renting specialized equipment such as lasers and various other items.
To remove the graffiti, five to six conservation science experts from the National Palace Museum of Korea's Department of Artifact Science had to work on site for around seven hours, starting early in the morning.
The National Heritage Agency is currently considering legal action based on provisional funding.
An official from the Gyeongbokgung Palace Administration Office said, "This is a tentative estimate of the cost of removing graffiti.
"We are currently seeking legal advice on how to respond," the National Heritage Agency and police said. On the morning of the 11th of this month, the National Heritage Agency and police arrested a man suspected of graffitiing the stone wall of Gwanghwamun (a matter related to the preservation and utilization of cultural heritage).
The suspect, Kim (79), was arrested and questioned for violating the law. At the time, Kim was found to have written black magic marker on the Musa stone (a square stone stacked in layers next to the Honggei stone).
He was caught writing "A letter dedicated to the people of the nation and the world" and "President Trump." The area of the writing was about 1.7m wide and 0.3m high.
The National Heritage Agency uses a blasting technique to remove graffiti from stone surfaces, using fine stone powder particles.
The act of graffitiing Gyeongbokgung Palace and Gwanghwamun is clearly an act of vandalism against cultural heritage. Under the current law, the perpetrator of graffiti can be ordered to restore the original state and the costs of restoration can be covered.
Immediately after his arrest, Kim was admitted to the hospital. Emergency hospitalization is a medical procedure for mentally ill people and those at high risk of harming themselves or others, with the consent of a doctor and the police.
At the time, police explained, "Kim has made statements that are not reasonable. We took into consideration the need for psychological stability as he is in his 70s and the risk of him reoffending."
