assuming a planet has high enough gravity, is it possible to just "pump" it's atmosphere full of oxygen to make it habitable?

Where are you getting that oxygen?

soil, let's assume there's a way to do it

Earth's atmosphere is 78% nitrogen and only 21% oxygen. I'm pretty sure you would not survive with oxygen only...

Maybe once we get fusion down.

No, because gravity isn't the only constant for atmospheric containment, also an electromagnetic field. Mars, for example, has none and may only retain atmosphere appropriate to the mass' gravity, and so it is very weak, and it will never hold substantial amounts of heavier atoms, they will only bleed off into space.

I STILL think that was a good idea.

Is this a serious post or b8?

Elemental nitrogen is almost completely inert.
