"Not by home users"
Just as long as it is difficult enough for the average home user. Of course if you can make enough money you will also attract more capable people who aren't easy to stop.
But when copying LPs and audio/video/software tapes was easy enough, a lot of people do it to earn money, not just to give a copy to the girlfriend. While when I was a teenager I could exchange LPs with a couple of friends because nobody of us had the money to buy all of them - but each of us bought some - I never bought nor sold pirated stuff, but there was some who attempted that to make money that way, it was far to easy to make many tapes, although of course to make hundreds you needed a professional copying machine.
