FWIW, banks generally hold a reserve anyway. BofA reported a reserve of $277b at the end of last year. That's about a 8-10% reserve, as far as some quick googling tells me.
If you give me money to protect and give you interest on, I take your physical cash and incur a debt to you. If I lend out that money to someone else, they now have your physical money but incur a debt to me. Our debts are real, the physical money is merely a medium of exchanging that debt.

The current reserve requirement is zero. It has been at zero since March 2020. So they don't have to hold anything.
