Well, pardon me for saying so, but it sound ridiculous unless you are entering a contest for the greatest use of fluffy words.
I think ineffable is too strong, and I don't see how inexorable can apply to a debacle, but debacle isn't the right word either. The strain on his wallet didn't lead to a debacle. You could describe the public response to his debauchery without contrition as a debacle.
This all seems to be correct. The sentence has clauses, which may hay caused you some problems. Since you haven't said anything about what has confused you in this sentence it is difficult to say more. It would be more interesting for me if you wrote something about how you understood it and the problems you had with it.
