Yes, if you want a fully functional cable you will most likely have to have the chip so it can properly route all the signals to the right pins, etc.
However, if all you want is a simple charging cable then a diode would work fine. Heck you wouldn't even have to have all 8 pins on the cable, just the 2 (or 4) needed to complete the charging circuit, and use a diode to assign the polarity correctly like he said. This cable could be made very, very cheap, and probably sold for a dollar or two at a profit. I think that would make many people happy. I know I would buy a couple. That's all I need in my truck or in my bedroom is a simple cable that can charge my phone. I don't need it to be able to sync, or have analog/digital out for the music etc. Then I could just keep the original apple cable in my office where my computer is so it is there whenever I need to hook it up to sync. Rather than having to go into my bedroom, open up the charging station, unplug my lightning cable, carry it to the office, plug it into the computer, sync, then carry the cable back to the bedroom and hook it back up in the charging station. Yeah it's not a huge amount a work, and I'm not losing any sleep over it, and obviously it's not enough for me to bother buying another lightning cable for $20, but it would definitely be worth it for $2-5 (which is around what I have paid for many of my fully functional 30 pin cables that I have in my bedroom, office, cars, at work, etc.).
