>As Enron and FTX both show well, personal criminal responsibility for high level executives and a "corporate death penalty" already exist and get used when circumstances warrant.
Hardly. Enron and FTX fell because they were insolvent, not because a "corporate death penalty" was levied on them.
Purdue, then, although a "corporate death penalty" executed in response to non-government-induced insolvency still seems relevant to me. The biggest proximate effect of shutting down a company is that all its employees become unemployed, so it's not something you'd generally want to do when there are other options on the table.
