That’s chapter 7. There are some debts that cannot be wiped out via bankruptcy. That’s true for corporations too. And when it happens, they get liquidated.
You can’t really liquidate a person and cease it to be an ongoing concern. The dynamics are different.
Chapter 11 can and does get filed by people - but it’s a reorganization, and buys you time to negotiate with the debt holders if able for a reduced amount or a longer repayment plan or reduced interest instead of going through chapter 7 where they’ll get nothing or very little if it’s unsecured debt.
