Why should the court enforce this measure?

The judgment of the court is a confirmation of the facts. Law can't restrain morality, just as it is the same reason that others owe you money. If he is willing to exchange with you, he will keep his word. If he doesn't pay you back, that is his moral problem. Since the judgment of the court is a confirmation of facts and a legal judgment of right and wrong, execution is a compulsory means to ensure the realization of the judgment. Whether the judgment can reach the content of the judgment depends on the morality of the other party!

The execution fee is stipulated by law, and there will always be expenses during the execution, which is also the basis for collecting the execution fee!
