there is high consensus on that, but not high enough to enshrine it into the constitution. in countries with strong rule of law, the courts have continued to uphold this whenever the state gets bold enough to move on a previously tolerated "baddie"

capital, as an aggregate expression of people's desires, moves like water. if will flow through any small opening

capital controls will flow through any weak link, whether that's a Shanghai free trade zone, a freeport at the airport in JFK or Zurich, physical cash, illiquid assets traded through a trust, or natively in crypto, or crypto wrapped within the same aforementioned structures, no matter what the prevailing or commoner's view is everywhere else in the region

even countries that can change on the whims of an all powerful head of state, they don't really mess with the capital because it drives everyone else away and reduces the head of state's own liquidity and economic driver.
