I understand that God can "want" whatever he desires but I'm not sure that it answers the question of" why". Throughout history many gods, if not all gods, have wanted worship. We could have every other positive exchange of emotion with God but worship is something different. I feel "bad" writing this but I'm coming at it from an Atheist angle. Some of them are saying why would God even "want" worship. Being all powerful He would not want anything, and worship does often come off as a requirement.
Let's try it from another angle.
God wants what is best for us. That means He wants us to be virtuous. To be virtuous is to possess and exercise the human virtues. Among the human virtues is justice, "the constant and firm will to give [one's] due to God and neighbor" (CCC 1807). It is the will to give everything what it is owed. It is, in other words, the will to respect the order of being as God has ordained it.
Now the order of being includes the fact that we are created by God and sustained in being by Him from one moment to the next. This fact alone entitles Him to constant worship. It is objectively right to worship Him. Thus, worshipping God is a matter of justice: we owe it to Him. He Himself cannot have ordained things otherwise, because He could not have made it such that we were not created by Him.
Now if a man cannot be good unless he is just, and if justice demands that he worship God, than God wants him to worship Him in order to cultivate the virtue of justice.
In other words, God wants us to worship Him not only because it is good in itself (although I think this is the proper reason) but because it is good for us to do it.
To refuse to worship God is to act as if one does not owe Him anything. It is thus to act in a way that denies our debt to God. Clearly, we do have a debt to God, so to refuse to worship Him is an act of injustice. Injustice is disorder, and when acted on knowingly and willfully, it is a sin. Thus God cannot even command man not to worship Him!
