Yes it is expensive now but the price will decrease in time. Technology will get better and become more commercial. You can already buy 3D printers that print candy. But that's not as advanced as 3D printing cells. Also you have to remember that most people can't actually afford real food. I couldn't find the video talking about the subject but what the food is really made out of in this video is pretty much what the average person can afford. The average can't afford to eat healthy fulfilling vegetables, especially when it's easier to just go out and buy some pig anus.
