You're standing in a spot ready to take a photo. You raise the camera with 50mm prime on it to your eye and the shot you want isn't quite framed correctly, so you're forced to use your feet to move.
I was standing on the edge of a cliff yesterday overlooking a beautiful waterfall but it was still a distance away. No other vantage point that you could get to up there to get that shot. So you had better have a large selection of primes on your back because sometimes moving closer or further away is just not possible.
I do agree with what you are saying in principle but I do have a problem with photographers who say that primes are the only way that anyone should shoot. (I know that is not what you were saying)
There are good reasons to use Primes just like there are good reasons to use zooms of every length. Listen to what everyone has to say and try the different methods but ultimately you need to make up your mind what works best for you in a particular situation.
There is a saying in music recording. GIGO. (garbage in, garbage out).
A prime lens will give a sharper more detailed image (depending on whose hands it is in).
I find I interact more with my photography when using a prime, which in turn has helped me become a better photographer. As has been pointed out already, only when you move, relative to your subject, does the perspective change. The importance of that fact is something you either grasp, or do not grasp but either way that fact alone, in my opinion, is reason enough to use prime lenses on the regular.I currently own a D750 with a Tamron 24

If you don't know what you're doing, I don't care if you if you take the most versatile hammer up the ladder, the shit's still going to be crooked or messed up.A good carpenter has more than one hammer and knows when and how to use each one. If all you're swinging is a 20 oz. Roofer's Claw then you might just have an issue when you try and drive brads without marring the wood. At the same time you're not going to want to down the ladder every time you want to swap weights or types, so you know to go up there with the most versatile one you've got.
