I think there's always a shortcut, the problem is that knowledge is always hidden or worse, because of dogma and tradition the shortcut is never researched & developed (had that happened, maybe the shortcut would have become the status quo).
Maybe what we all see as a "shortcut" is actually the "true path", and most of everyone has been using inferior methods. Rather than call their own methods inferior, they instead classify the alternative that is more effective as a "shortcut", as if it violates some kind of presumed "natural order".
Is the LBRP a "shortcut"? I'm sure there were more longer and complicated banishing rituals that people used in the past. The reason why the LBRP became "standardized" and so well known is because it was efficient and effective, and that made it superior to a lot of the others because of it's usability. I'm sure some people from the far past would call the LBRP a "shortcut" but to us in modern times it's just the status quo.
Also, maybe to some people the tradeoffs of "shortcuts" are negligible (so to them it's not a "shortcut") while for others they are not worth the cost.
Usually the methods that people classify as "shortcuts" are methods in which they see the tradeoff as unfavorable and the cost as too high and not worth the risk. But that's just their perspective, if they had a different mindset that "shortcut" would be their "obvious choice" and their first choice at that. Something is only a "shortcut" relative to the alternative you are comparing it to and your own desires.
For example, imagine there was a "spell of ultimate power" but it made you impotent so you could never have biological children. To the average person that would probably be too high of a cost, but to people who don't want children anyways it's a no brainer because it's a win win.
To someone raised in an environment where selling drugs and making quick cash is the norm, it isn't a "shortcut" to working a 9 to 5 job, it's just a regular part of life to them and it's the expected path to take. To the person raised in an environment where everyone is working a job for income, selling drugs is a "shortcut" and the risk of jail time isn't worth it.
