Yamuna amma, namaskaram.
To give a short answer, it is better to follow what appa says.
Now the long explanation: Each one of us have a certain preference in many things. Even in seeing Perumal, we like to see Him in certain ways. For those who like to seem Him in all richness, He appears as Dwarakanath; for those who like to see Him in all simplicity, He appears as Gopala Krishna in Vrndavanam. Both ‘All Richness’ and ‘All Simplicity’ are His glories. Some of us like this glory; others the other way. But even those who prefer to see Krishna as Dwaraka Krishna, they also find Gopala Krishna attractive; vice versa – Those who prefer to see Krishna as Gopala Krishna also find his Dwaraka Krishna attractive.
Similarly, whether He is Raja Rama in Ayodhya, or He is in the forest dressed in tree barks, He is beautiful and attractive in both forms. Whether He appears as innocent little Vamana, or ferocious Narasimha, or even a wild boar as Varaha, He is always attractive.
We can focus on how He is attractive whichever form He takes, and not limit ourselves to appreciate only one way. Ultimately it does not matter what we like; what matters is what He likes and what gives Him pleasure.
One thing that easily pleases Him is, if we follow the system He has given us. To follow appa’s guidance is a Perumal created system; especially in this case appa is also a devotee. He is not saying anything atheistic like Hiranyakashipu said to Prahalada. So, we should follow appa. Also, what appa is suggesting is similar to what is followed in temples. In temples also they don’t leave the ornaments on the Lord all the time; different ornaments are used in service of the Lord at different times; at other times they are safely stored away. It is also our duty / kainkaryam to protect Perumal’s property from getting lost. With this view also, we have to do whatever is needed to keep it safe, so that it is available for use during festival days and other such occasions.
