And assuming the crypto algorithm has no fundamental flaws, it's applied correctly, and the software implementation has no bugs.
All of which are things people have on occasion believed to be true and found out later they were wrong about.

I mean I don't think it's unfair to say that most of the battle-tested encryption is "uncrackable enough" for the consumer.
If you're working for the NSA you need to worry about these things being cracked, obviously, but for the "I don't want a scammer to buy my laptop and get my social security number" situation, I think that you really can just assume that LUKS is uncrackable.
That said, it takes like five minutes to boot a live Linux flash drive and run fdisk to delete the partitions and/or install Mint or something over the existing data, so I don't really see any reason not to do it, even if it's not strictly necessary.
