Erm actually... tastes and smells are replicated, plagiarized and generated all the time. Touch less so but it's definitely a factor in a lot of industrial and product design.
Well, it is not like we copy a file that has some bits and bytes of data, and boom, you got the taste, smell and touch.
There are entire industries that exist outside the realm of computer science, and forms of "data" that don't exist on a disk. Look into the perfume industry, for instance. Do you think no one has ever tried copying Chanel No 5? Flavors can't be copyrighted but many restaurants and food manufacturers protect them as trade secrets - see KFC's "11 herbs and spices."
