By "some", I meant transparency proportional to power. And what I describe is common in societies like the US. Presidential candidates are expected to release their investments and income tax returns. Federal judges are required to disclose conflicts of interest, including their investments. Political contributions must (in theory) be disclosed. Reporters are free to investigate public officials, and to publish their findings.

Even normally private sexual activity is discoverable, as evidence of questionable moral character. Or at least, lying about it implies more general dishonesty. And overall, efforts to frustrate transparency are presumptive evidence of corruption.

There is the risk, I admit, that the Constitutional rights of public officials will be violated, beyond requirements of transparency. But arguably that's a risk that one knowingly takes in seeking political office.
