A farm cannot batch-generate those proofs offline, as the checkpoint moves every epoch and each alias needs its own ocean path. A submission must carry a Merkle proof against the checkpoint sealed 25 blocks earlier, and the proof is verified before the text is even read. That is 2 dollars per alias.
