When you look beyond the whole "I want one because I can't technically have it" argument, the AK is inferior and far less evolved to some of the NR options we now have available (for target practice / hunting purposes, of course). Plus a lot of these new options also cost a hell lot less than even a stripped M78 receiver would, not to mention a complete Valmet!
I'm sure that if you gave the antis of 2014 the choice between prohibiting some clunker-ass semi auto "AK variant" vs. some of the high tech "scary" bullpups & co we now have on the market, they wouldn't think twice about it. They would let you have a semi AK in a heartbeat if it meant taking away your T97, Tavor, etc... Truth is, the AK has outlived its' usefulness for the modern military and is no longer considered "the best choice", unless you're a child soldier somewhere in Liberia and your warlord only has 50$ to spend on arming you. Even the Chinese PLA, with their millions of soldiers to arm, have moved on from the AK design in favor of something new and more suitable to the 21st century. Comfort and versatility are the key today. That is true for soldiers, sports shooters and hunters alike, hence why we see so many civilian versions of those new designs. Not that anyone's complaining (except for the ever fear-mongering antis).
Best thing is, with the use of modern polymers, these new age rifles can be built faster and cheaper than the all steel & wood dinosaurs of the 1950's, à la AK. All in all, prohibited or not, we're not missing much. Think of the semi-auto AK as an SKS with a better looking factory stock, that's all... lol!
