It's more akin to refusing to manufacture kitchen knives and forcing all the chefs in your kitchen to chop things with spoons. Even though anybody who wants to stab people already has easy access to very big and sharp knives just by stepping into any other kitchen in the world. Also lots of your chefs keep sneaking over to the kitchen over the road to chop things and no newly trained chef wants to work in your kitchen because they think only chopping with spoons is stupid and only done by crazy religious old men with big beards. OK this metaphor is getting pretty stretched now.
