There are millions of publicly rich people who get around just fine.
Agree. But to me BTC gets "stratospheric" only in a post-state-situation where states have collapsed and BTC becomes the new FIAT and in such a situation you have basically no state on your side that guards you as a rich person. So you go and buy a house and the next day some idiot just comes and moves in with his family.

Then you need a special security company that helps you to get that asshole out of your house and you hope that his security company isnt better/more capable than yours.

But now we are way OT cause those are basically issues of anarcho-capitalism.
