The other issue is just because something doesn't need to be hidden today doesn't mean a change in the political/social winds could happen that requires you to hide it tomorrow.
No. Sorry. This is invalid. It would be pretty bad if we declare some shit illegal and retroactively apply the "law". You will be charged for shit that everyone did and is perfectly fine. For example: How would you like to go to jail for not being a Christian? This will be weaponized.
That’s the second time I see bank account number framed as something private. Why? It doesn’t authorise anyone to do anything. It’s not like a debit/credit card number.
Your social security number? Your bank account number? Your debit card PIN? Yeah, pretty sure you have something to hide.
