Why do Covenant Abilities/Restrictions remove player agency?

That is only for, let my quote a person who said something very accurate

For me and for others who make our own choices and builds, thinking exists.

For them, choices will never exist since they will brainlessly follow the guide, and they will also follow the same guide saying that they should change to x talent for X boss, so as you can see for those people there is 0 RPG elements in the game either way
