I’m sorry perhaps I misunderstood “entitled” I assumed in this context you meant aas in have a right to or it is a correct act, which you clearly say in your op it is not.
You didnt reply to my point. There are many places in halacha where “favorite food” is discussed. whether with kedima librachos, or which Shabbos meal to eat them etc etc… how do you explain this if not only is having a favorite food is so bad but even for children!
As for your point here are some of dozens of posible replies:
1) There are shitos that argue on the metzudos david
2) That is a goal to strive towards for yechidim
3) He means food shouldnt be the thrust of your life, but there is nothing wrong with the having a favorite food
4) Even if food is eaten primarily to serve Hashem it is still allowed to taste good. Consider the mishna “pas bamelech tochal” Even if limited to bread salt can be added to enhance the flvor
