Sorry, but the state just confiscating 5% of someone's net worth (unrealized or not) is absolute madness, and rightfully opens up questions about slippery slope, how "temporary" they claim this to be, and so on.
It's not surprising they are leaving the state or using their resources to try to stop it.

This is not a normal state of affairs.
Should we move on to anyone with a net worth over $1M and start stealing their assets too?
