...ah, okay. Well what I was reacting to was the fact that stabbing your horse with nails is what will actually happen if you try to shoe your own horse and you do it badly, as the inner part of the hoof is "alive" just like other parts of the body and can definitely not accommodate any nails. So the difference between stabbing your horse with a nail and putting the nail where it belongs is something like 5mm, and you have to hit that while the horse (which may be 10x your weight) won't hold still. If it weren't for that minor detail, everybody would just shoe their own horse.
But you probably won't get arrested for attempting this and getting it wrong.
If you have a well-behaved horse and you take a course, like they have in those trade schools in the U.S., where they give you a hoof from a cadaver and just let you practice driving a nail into it 100 times, and then you do it a dozen times while getting feedback from a pro, then it seems quite doable. But those courses don't even exist in Germany, as the trade is that keen on preventing these kinds of skills from becoming too widespread.
