This must mean that Bitcoin will eventually seize to exist? Or at least shrink to minimal amounts, when it shrinks to a certain level, it will no longer be useful.
Is this correct?
It`s correct that less bitcoins in circulations is actually a good thing for the people who have some bitcoins, less supply and high demand will push the price up. What I don`t understand is what countries can do about bitcoin? It`s not up to them, everything depends from miners and what they agree to do with chain. You need to learn a lot about bitcoins, bitcoin forks, and who have a vote on the network, countries can just watch if they don`t have some hash power under their control. Bitcoin will not die, this is just some not so logical thought in op`s mind, don`t spread spam and mix things in your head, inform yourself about bitcoin before making this kind of statements.
