Depends on how you do the capture. If you need to engineer the system and feed it energy in a form that we can instead use to power other stuff, then yeah, it doesn’t make sense. But if you for example, plant a tree, then that tree would use energy from the sun that you wouldn’t otherwise be able to use as easily.
The carbon captured by the tree will be released when it eventually rots or burns. That’s why it’s called the “carbon cycle”.
If you want to reduce carbon in our atmosphere, you need to capture and store that carbon in a way that won’t be released again for thousands of years or more.
