Oh, I understand perfectly. Its just a huge misunderstanding on alot of folks that you can hollow out a pipe and its more rigid or stiff. A 1/2" bar stock is more rigid and stiff than 1/2" bar stock thats been reamed out.
talked to my uncle he said you can flute or ream out a piece of bar stock to degree and have the same strength and rigidness as a solid piece just the fluting or reaming for the most part just makes it lighter in weight.
