" You were originally trying to set up a that i claimed that "citizenship = agency" as a straw man. "Nope. I said that "citizenship = agency" is the only downside presented IN STORY. You claiming denouncement prevents that because that's the ONLY way that denouncement preempts the government from claiming Superman is their agent in your flawed logic. You said it right there up in the quote.
""While Superman is percieved as being an US citizen serving US interest, the US government can misrepresent Superman's actions as reflecting their authority and misrepresent Supes as their national weapon as a sort of means to assert more influence and power internationally. [that is, agency, look up the word] ...I said that the government could use the perception that he is a US agent in ways that Kal-El's moral sense wouldn't approve of. By denouncing his citizenship he was effectively fighting against the possibility of any misinterpretation of him or his actions leading to any unjust consequences."
You are, ridiculously, trying to link citizenship with agency and saying that by denouncing citizenship, Superman can immunize himself from claims of agency- whether by the government or construers. This is absurd.
