The thing that you and others cannot seem to grasp is that secession does not require justification. The Declaration of Independence is quite explicit in saying people can have independence for any reason they see fit.
This is what you keep calling "at pleasure", and that is in fact true. People could have independence "at pleasure" if they wanted it.
And why not? What is moral about a forced coerced relationship? Sounds like slavery to me.
And yet... and yet, most seceding states did issue "Reasons for Secession" documents, justifying their "whereas's" and "wherefore's".
Nearly all of these documents focused on slavery, none mentioned the endless nonsense our Lost Causers have since concocted.

That is a pure figment of yout overactive imagination.
In fact it neither says nor implies any such thing.

No Founder ever proposed or supported an unlimited "right of secession" at pleasure, meaning without serious reasons such as those spelled out in their Declaration of Independence.
