I totally guarantee that I understand the concepts of density and buoyancy better than you do. I also make a similar promise about atmospheric pressure.
Some questions I guess since you would prefer to do this as a teeth pulling exercise rather than no. But first, let me just out of hand reject this "statement":
"It should be completely apparent even if you do believe in gravity that the primary action on an object will be from density and buoyancy."
Note that I am rejecting that statement because it's jibber jabber. It is literally meaningless. "Primary action" is not a term that has a definition that is either commonly or uncommonly accepted.
1. Why do objects all fall with the same acceleration in a vacuum regardless of mass or weight?
2. What causes atmospheric pressure?
3. Using buoyancy, explain why an object when released accelerates downward.
4. If buoyancy is the be all and end all you portray, why can I put a very dense object on a less dense table without the object falling through the table?
5. If I release a very durable weather balloon filled with an incredibly non-dense material, what happens to it?
