Reply #2: An interesting question I hadn't considered...

[Rabrrrrrr]

though I think I could say that the only ethical option is not even to have sex.

Otherwise, we'd be looking at either forced abortions or forced putting-up-for-adoption, and neither of those are sensible or moral, in my opinion.

But I do think it is a logical, and perhaps even okay, conclusion, given the premise that it is unethical to have children one cannot afford, that one cannot have sex ethically without having the means to support a child (unless one is willing to have an abortion or put a baby up for adoption).
