No, it does not need a meaning - outside of beings that experience need
This is a fascinating concept. There are various directions you can take this in: of course, there is "need" on a conscious level, which is essentially what you've discussed, but then it could be argued that everything which exists also exists
with need of certain conditions. For example, the chair needs materials, design, constructiona and maintainence. It also needs an atmosphere suitable to house it, and it needs to not be set on fire. Stuff like that. And, more universally, planets need gravity, a star to orbit, etc.
Biological organisms have an innate purpose that they were designed for ... that's procreation
Now
there's an ideology I can happily buy into!

People can live a perfectly "happy but pointless" life in hedonism, for example (or rather, the only "point" is having fun)
I try to live a hedonistic lifestyle as often as possible. Sometimes money, circumstances and the general sufferings of everyday life get in the way, but whenever I can I go after having as much fun as is humanly possible. When it comes down to it, that's all there is for most of us.
I tend to think of myself as a generous hedonist though - it's not enough for just me to be having fun, I like to know that others around me are also having fun. I love working the room when there's a party, for example - I'll move around regularly and talk to everyone, tell jokes, top up people's drinks, get people dancing and make sure their song comes on; I have to know most of the people there (or have had a few drinks!) to feel comfortable doing that, but when it all comes together I'm in my element
