OK, so it seems like the transaction is not really done off chain, but instead, all metadata for the transaction is just not necessarily stored on chain?

for example, in the early days of spaces protocol, there won't be tons of subspaces per space, so if a subspace wants to be delegated, they aren't going to want to wait days or weeks for the space owner to have more transactions to aggregate delegation of, so each subspace transaction is practically going to require a single on chain transaction if there is no others to aggregate with?

i guess I'm trying to understand if this has a similar paradigm as zkcoins and taproot assets?
