What exactly is wrong with losing ownership of the money? Deposit insurance covers in case of a bank failure. It's technically a IOU, but the possibility of not being able to withdraw their is slim. What you're arguing over is semantics. Yes, the money deposited in a bank is an IOU, but for all intents and purposes it's just as good as real money.
If all the people go to bank and withdraw their money, there will be a bank run. Just like FRB, FDIC is another level of insurance to calm down depositors. If all the banks facing withdraw pressure at the same time, even FDIC can not payout that much money. FDIC only have $100 billion at hand to insure about $10 trillion deposits
But what I argued was that IOU "all intents and purposes it's just as good as real money". Yes, there's a tiny risk of catastrophic failure if the bank fails and the deposit insurance fails, but people accept that risk in exchange for convenience and security of their money, compared to stashing them under their mattresses. People not are misinformed about what happens to their money when they are making a deposit, so I'm really having trouble seeing the issue here.
Also,
For example, when a commercial bank loans money deposited with it, this bank does not withdraw that money from the borrowed account. So the loaned money must belong to both its borrower and its loaner
No, that's not true. In this case, the bank has a IOU to the depositor, and the lender has a IOU to the bank. The money belongs to one person only: the lender. The bank has a fraction of the deposits in cash for customer withdraws, hence why the bank can also fulfill the depositor's withdraw request at any time (to an extent).

If you cannot see anything wrong with losing ownership of your money, then why don't you give it all to me?
Because:
- you don't have deposit insurance
- you can't give me my money at moment's notice
- i don't know or trust you
- you are not bound by any government regulation or audits
