The OP may not be crazy, but must be young. Decades back racks exactly like he envisions were the norm. These steel racks were soon displaced by lighter die cast aluminum racks, specifically those from Pletscher and their ilk. In turn, Pletscher racks lost favor to welded racks which claimed to offer greater stiffness.
I don't claim that we've reached an endpoint in rack evolution, and may see new designs that move from welds, but winning design doesn't always win in the market place.
