That's not true. Not only do some of us get a sense of satisfaction, seeing our characters grow. Having a character progression system also gives you control over which gameplay elements that you want to expand/get, it gives strategic choices in terms of how you want to develop your character, and having a properly implemented character progression system can also work as a way to "open up" the world. That orc that kicked your bum 3 levels ago can now be beaten, and you can finally see what it was guarding. It does not only give you a nice sense of progression, seeing your character be able to do things that it did not use to be able to do, but it can also be a good way of foreshadowing things to come (show what you'll be going up against later, or heck even what you'll be capable of later).
It might not be true. It cant be infirm though by providing elements that confirm it.
Which is done in the comment.
The comment shows that players say what they want, not what they desire.
The best part is that game devs already probed players' desires and answer it to the best possible.
It also confirms that this kind of question are pointless in a dictature of tastes and likes.

This was never objected against.
It simply means that players get a sense of satisfaction out of a endless process.
Growing for growing is a cycle with no end. Growing from nth stage to (n+1)th stage. On the paper, it has no end.
Now when players desire the point of being unchallenged, it sets a value for n. From a certain value, the PC goes unchallenged. It has an end.
This simply means that players get a sense of satisfaction out of an ended process.

A few posts above, it was about keeping the PC challenged.
A new demand appears. Putting an end to a challenge.
Up to level 3, the orc is challenging. Beyond level 3, it is no longer challenging.
This changes the situation, from being (permanently) challenged,it turns into putting an end to challenging situations (constantly)
Players do not desire to be permanently challenged, they desire to put an end to an endless stream of challenges.
No matter how many challenges they have put an end to, they want a newer challenge.
This means that the gameworld must grow constantly.
It must grow though in a certain way: it cant grow in 1 to 1 proportion as this would mean the orc remains challenging forever (showing once again the uselessness of the character progression system to meet the demand of a permanently challenging world)
It must grow in a way that until the PC has met a threat, the threat grows to meet the challenge. Once it is met, and past a PC's growth point, it must no longer be challenging.
That's level scaling. Devs already brought a suitable answer. In current conditions, in all likelihood, the only suitable answer.
