You can't really stop a government from borrowing except by taking away the power to print money. Grab your popcorn and watch Italy a.k.a. "Greece: Part II" over the next year to see what happens when government overspending meets currency it doesn't control.
The debt ceiling isn't in the Constitution, and, as such, doesn't really demonstrate anything relevant. OTOH, all wars are characterized as defensive, and the US has usually been at war, particularly in the times of concerning deficits; aside from—if construed to require formal declaration of war for borrowing—making declarations of war more common, I can't see that the proposed restriction really would have changed much even if it existed and weren't amended out.

Taking away the power to print money prevents monetizing debt, but it doesn't prevent borrowing (it actually eases borrowing, which is one of the reasons for having independent central banks separating monetary from fiscal policy; the degree of perceived risk of debt monetization makes borrowing more expensive, so controlling that risk facilitates borrowing.)
