Technology advanced a ton since the last time it happened. And food making is no longer that lucrative. Other industries give more opportunities for corruption.

Besides, I don't advocate for nationalising entire food production. Just carving out small segment that by design operates at a loss because it acts altruistically not with market ruthlesness towards consumers.

It can be trusted as well/bad as for water, electricity, security…

It about quality food being vital for everybody, not about importance. A public “default food package“ could have a big impact for many families health. The private options can stay , regulated, as well as for water, electricity and safety.
