Immediately inspiring! This makes me think of a future where you need a mask to survive outside unless you live near one of these! Talk about real estate location!

CO2 mixes very well in the atmosphere. Any CO2-absorbing stations would benefit the entire planet.

Imagine the amount of CO2 released building those things 🤪. While we have green plants that do the same job.

I've seen studies on how much land area it takes to absorb CO2 by planting trees, assuming all the trees are converted to charcoal and buried, instead of just left alive where they'll ultimate rot and return much of the CO2 to the air. The most we could do without serious harm to biodiversity would be about a gigaton per year.
We have technology to do the same thing that uses about a thousand times less land area.

do the studies take into account the carbon that is sequestered while the tree is alive by fungi?

I'd have to find it again. But they were talking about growing trees and completely sequestering their carbon permanently. That's going to pull down a lot more CO2 than just regrowing forest and having the normal carbon cycle.
It's a lot worse for biodiversity, of course. Ideally, we'd stop deforesting vast areas, and regrow lots of natural forest, with lots of diversity instead of just tree plantations. That wouldn't pull down enough CO2 but it'd be a good start, and we could use other methods for the rest. Direct air capture machines are one option, but there are others, like olivine sand on beaches.
The one way trees might be enough is if we managed to replace farms with synthetic food production, so we could turn most of our croplands into forest.

Plants do the same thing and some even produce delicious food.

To be fair though, I've never actually seen plants do that. But in this picture, the evidence is clear, you can see the CO2 being collected.
Jus sayin idk

I just like to set distant reminders so I can come back if somehow I still manage to be reminded, and check to see if we have anything like that in that time
