Nice one, Goq.
The Gra says that one of the most difficult mitzvos to fulfill is that of v’samachta b’chagecha. It’s not as easy as buying a new top. Hashem gave each of us the means to find true happiness within ourselves. That’s why it’s so difficult – because it’s inside of us, and we need to bring it out by arousing our neshamos through tefillah or talmud torah or hisbodedus, thinking of the beauty in creation or the incomprehensible wisdom of Hashem visible throughout everything in the world. Perhaps the above-mentioned halachos are meant as an aid for people unable to extract such simcha without external help. Just a thought.
Be happy!
