I somehow disagree with your disagreement. If you have a Bugatti and live in a mansion, no one really knows how much exactly you have. They might break into your house and rob some stuff or your car but most of your wealth is probably somehow protected, in banks, real estate and other financial third parties or instruments. Hard to get to those!
And while I agree that Bitcoin has the property of being unconfiscatable, you don’t want to be in a position where you are a target. There are stories from the UK, Canada and Sweden among others, where criminals broke in, tied down people for hours and finally got ahold of seed phrases, access to wallets, etc.
It’s easy to think we are all tough guys, ready to defend what’s ours (we should be!) but it might be a different story when you have a family to protect and a bunch of violent guys decide to pay you a visit.
Don’t wanna scare anybody with this, we should be out building community, spreading the Bitcoin wonders and teaching to those who are ready for it, but a little bit of prudence and privacy in managing your wealth should be encouraged.
