It seems to be a personality clash between him and you.

Set a mutual agreement on his responsibilities: such as that he should finish work by whatever time, then he's free to do whatever he wants. This way, he'll have more incentive to do it.

Don't interfere too much in his life. Help him to learn how to make decisions and live with the consequences. Stop the urge to intervene. If he is a relaxed guy by personality, there is nothing wrong with it.
