Example... the following is illegal in Thailand
1. Prostitution
2. Going out of your home without wearing underwear
3. Swimming across the river without carrying a coin
The article just sounds like the government advised them that its illegal.. basically saying "we have not declared it legal and at this moment we don't think its important to spend time and resources thinking about it.".
3 is a joke I suppose? :p
In the article mining is NOT mentioned as illegal

2 and 3 i just stole from some site after googling... Having lived here for few years it seems very plausable.
mining is not mentioned as legal, hence its illegal. Your argument is invalid.
