No doubt.  But banks will either become part of the bitcoin ecosystem or die.  On-chain fees will become too high to make any sense to use for everyday transactions.

If a bank advertised, "FEE-FREEE BITCOIN TRANSACTIONS", that would be enough to lure in customers. 

 Eventually the mempool will clear again once enough people use lightning wallets, or other Layer 2 solutions.  I don't think the ordinals insanity will continue on forever.
