Not that they’re the only ones willing; but they are overwhelmingly the only ones capable of operating in the way OP describes due to a variety of societal pressures, lack of family attachment, confidence/ego, etc. Other people are certainly willing and able to work hard and independently, but you do have to provide more formal guidance because you cannot expect someone living in a different cultural context to meet all the standards you hold yourself to. There may simply be a misunderstanding, and because I guarantee the employee would be acutely aware of the understanding gap, it’s on the manager to be aware of it as well. Informality has a lot of benefits, but it’s also necessarily exclusive to people who don’t know the unwritten, informal rules under which you operate. This can and will lead to a homogeneous team that seems productive from the inside, but may miss other goals because they’re just unaware of them.
