You need to think material versus process. A little furniture “history” would help as well.
The style of your table is decidedly “old world” blacksmith-ed ironmongery. To achieve the visual “weight” of the structural elements they would have to be cut from something like 1/2" plate (to resemble 1/2" bar stock). And as simon points out, the waste would be significant, and considering the rising cost of steel not at all profitable. You could bend this material if you applied heat from an acetylene torch… but keeping all those bends in the same plane would be a challenge. CNC bending equipment would be the best route for any serious production quantities.
If you are piqued by laser cutting, consider the following example… not of my particular liking, but it certainly illustrates the capability/technique.
