No sane person would ever depend on a stranger, simply on the basis of possessing extraordinary abilities. Society enforces checks and balances to limit the potential corruption, misuse of power, and general political influence a single entity can hold, usually through regulations and policies that public servants are forced, not recommended, but involuntarily obligated, to abide by.
Comic book fans seem to be under the impression that costumed vigilantes are permitted to ignore regulations, break all laws, and defy all policies under the pretext that people would understand their motives, simply on the basis of a moral code these costumed vigilantes claim to follow? No one with a claim to sanity would fall for this poor line of reasoning.
Also, Lex Luthor is a hypocrite. He rants about the risks and dangers of aliens, metahumans, and supernatural beings, but this is a man who: possesses an advanced exoskeleton originally designed by an extra-terrestrial, was a former metahuman through the access of a serum, and once obtained supernatural abilities by procuring a magical ring.
