It's also a bit of a straw-man to put your own version of what someone's saying in their mouth.
Buying insurance and other mitigations against rare circumstances, outside of well regulated and well understood products in stable marketplaces, is really hard. You need to do your homework with the counterparties and be sure that incentives align well enough to get what you want.
Unfortunately, when you set up an incentive system, you tend to get exactly what you pay for-- whether that's what you want, or not.
Read the report. Power systems are complicated and not as easy as just "build another nuclear plant". It was (by regulation) conventional units that were required to provide voltage support, and it was in part their failure to operate according to their requirements that lead to the voltage excursions that caused the system collapse. The renewable systems that were capable of providing voltage stability were not allowed to do so.
