Engineers design passenger aircraft, rockets, cars, and medical devices without needing licenses - the products themselves are strongly regulated. Requiring the engineers developing the product to carry licenses will just raise the overhead cost of developing such products. I think the key difference is certifying the product when there are multiple instances of the product being made is cheaper. For civil engineering, most of the projects are unique (and even if the design is something of a copy - then the sites present unique challenges). So maybe it makes more sense there to license the engineers.
