I think there's a language barrier here

The article talks about
dispelling myths that treat training is bad. Go back and read it again- it actually talks about why treat training is a useful tool. What do you mean by "using the rope to make him obey"? Leash pressure? That's also another good tool. Personally, I want to build drive and the bond with my puppies, so I introduce things with treats as a reinforcer and they're useful for luring. Dogs understand that food is good; it's an easy thing. They can eventually come to understand that praise alone is good too, but that's typically done with food first. I don't want a young, young puppy to have to think about the world in terms of "you must obey," it's a really good way to squash drives and end up with a dull dog... I made that mistake. You want puppies to learn behaviors because they're fun... the "obey" part comes later. I start with treats while I'm teaching something new- they're useful for luring and shaping to get the dog into the position I want for that behavior. Once I can expect that the dog understands what I'm asking, I slowly extinguish treats using a sort of random lottery reward system. I want my dogs to learn to want to work. Eventually, once they're older, I do expect obedience, but that comes later. Even when they're adults, I still use treats for teaching new things and as rewards for certain things.
