I use my computer to read books, for example. This eliminates the central manufacturing of books; when I want to read a book, I tell my computer to turn into a book, thus manufacturing one temporarily on my desktop until I'm done.
I use my computer to graph equations. This eliminates the central manufacturing of graph paper; when I want graph paper, I tell my computer to turn into graph paper.
I use my computer to make telephone calls. This eliminates the central manufacturing both of telephones and of telephone switches; when I want a telephone call, I tell my computer to turn into a phone, and it turns routers into phone switches.
I use my computer to watch pornography. This eliminates the central manufacturing of porn VHS tapes; when I want a porn video, I tell my computer to turn into a porn video.
I use my computer to store books. This eliminates the manufacturing of bookshelves, although to be fair, bookshelf manufacturing has never been as centralized as computer manufacturing.
I use my computer to do engineering design. This eliminates the central manufacturing of drafting tables, slide rules, and pocket calculators.
I use my computer to find out what time it is. This eliminates the central manufacturing of wristwatches.
I use my computer to send letters such as this one. This eliminates the central manufacturing of envelopes and postage stamps.
I use my computer to find out about Syrian children drowning in Turkey. This eliminates the central manufacturing of newspapers, although again, this may not have been as centralized as computer manufacturing is.
Perhaps this can help you to understand in what sense the original statement is true, as well as the sense you've already pointed out in which it is false.
