For now, Taquito doesn't work with entrypoints that require a value of type contract, so you cannot call the balance_of entrypoint of an FA2 contract from Taquito. In general, you wouldn't need it because the entrypoint is reserved to get the balance of a user on-chain. With Taquito, you can read the balance directly from the ledger bigmap in the storage.
