To your points:
> gold-diggers
I'm not sure if this is an idiomatic term and out of my grasp, but if you mean that people will get romantically involved with others because of their money... this is a non-issue. Happy to debate it further, but it seems so silly and self-apparent that we shouldn't care at all about it
> Invasion of privacy
Arguably, but as long as only a minimum amount of whats is public, with only the lump-sums published, I think its fine in context.
> It's almost as bad as having medical conditions and STIs test results listed publicly.
I think these are very different things, the difference is not just of severity. They are different classes of things. Financial information relates to money, which only makes sense in a society (money is for trade). A disease's effects are personal. When they aren't, you are obligated to disclose them and/or to comply to other rules (for example, to quarantine).
> Facilitating public exposure of counting other people's money doesn't help anyone except the rich to know if you can fight them in court or how much to bribe them.
I think the experience where this has been applied is precisely the opposite - the rich are the ones affected the most. And - if your justice can be bought, the problem has less to do with the knowledge that the other can't find back and more to do with the legal system in the first place.
> Fight wealth inequality with income-&-holdings-proportional fines; simple, government-calculated graduated taxes without complicated exemptions; elimination of corporate/wealth welfare; and expand economic-advancement-oriented welfare to those who aren't super-rich who can use it.
Can't argue with that, even if I wanted to, in fewer than 15 pages. Complex stuff!
