With Pelosi specifically, this doesn’t include her husbands trading.

Which is absolutely still relevant in the insider trading allegations. Not just immediate family, but extended family and close business associates are included in that round up.

This is a fair point, and definitely a family involved in politics could take advantage of the system this way.

I’m not sure how we resolve this. I can certianly see a justification for elected officials having essentially open books, their investments submitted to public record. But does the public have a right to an official’s spouse’s account information? Their children? Their parents? Their siblings? There has to be a privacy line somewhere, but of course a bad actor could just run their accounts through a family member on the other side of that line (as you said, through cousins).

I can’t think of an enforceable rule that could prevent this, that isn’t also an egregious violation of personal privacy.
