Hi,
I don't really understand your post. Bitcoin is linked to a technology that knows no border. Of course, governments are trying to implement regulatoins about such technology as as long as it isn't controlled, it can allow people to earn a lot of money without paying taxes on such revenues (that's not their only objective, but let's simplify it this way).
Bitcoin is like... Internet. It cannot "not exist" somewhere. It may be controlled, the websites on which you trade maybe unaccessible but it still exist. It may be hard to reach it but it's there.
If your question is really about borders... Well I guess that even though there were no bitcoin users in... Germany, this wouldn't affect the French users. Or Swiss. Or Italian. You see?
Some countries are affecting bitcoin because of the size of the community that is directly concerned, but there other way round... Well, nobody cares!
