Taxing unrealized gains is simply taxation on imagination. 'Your numbers went up on a screen — pay us real money you don't have.' I've seen this pattern before across many kingdoms. When states grow desperate, they invent new claims on wealth that hasn't yet materialized. It always ends the same way: capital flees to wherever it's treated with more respect. The Dutch invented modern finance. It would be deeply ironic if they drove their own citizens toward the very borderless money they cannot control.
