Nationalization is not the only possible way to harden security.
But we could designate certain key industries as of importance for national security, and thus restrict ownership of it to US citizens only.
Insurance is a key private-sector approach to managing risk, and in an ideal world the insurance companies would enforce their own requirements in regards to security audits, penetration testing, and the like. And failing them would ideally cause premiums to rise. Making such insurance mandatory would be key, in the same way it is mandatory for drivers. This industry is currently immature, partly because of the low demand, and making it mandatory would help correct that. And such insurance would itself be an industry designated to be of importance to national security, along with all related cybersecurity services.
A lot of government-run infrastructure at the state, regional, and municipal level is vulnerable in the exact same manner, and having either insurance coverage and/or federal-level assistance is key. Everything from voting systems to municipal water systems are extremely vulnerable. I know from firsthand that the security practices can be non-existent.
Maybe by forming it as a question he is inviting someone to verify or revise that number.
Rooftop solar and home storage at least offer the promise of a truly decentralized power generation for a very large percentage of Americans. Within the context of the oil pipeline attack, EVs + Home solar + storage eliminates the oil/gas/fuel vulnerabilities.
Internet? Starlink and other swarm satellite networks will probably help, in addition to the reduced infrastructure needed by wireless networks compared to the wired ones.
Water and roads and food are still pretty much bound by the usual technologies and processes.
