Are Erasure Codes (Storj) better than Replication for the SAFE network?

So if you lose A for example then the network would require to make a copy of A, to do that nodes would need to get copies of B & C to recreate C.

To make sure I understand, I assume you mean recreate A instead of C in the quote above?
I’m not a RAID specialist, but that is something like RAID 5.
I see the problems you describe, certainly if n and p are rather big numbers.
