You cannot "own" #Bitcoin in the traditional sense of owning stuff.
No matter what governments, courts, chain-anal people, or anyone else tells you, there is no way of proving that someone DOESN'T know a string of information such as a private key.
From this perspective, satoshis aren't ever transferred but rather reorganized on the timechain for communication purposes.
The twelve magic words do not belong to anyone. They're just twelve words.
What Bitcoin makes so blatantly obvious is that money was never anything but information.
A ban on "self-hosted wallets" is as absurd as a ban on using your brain.
Such a ban would have severe consequences.
It would deny you the right to keep a secret while granting the government the right to claim that you do, making everyone a criminal.
YOU would have to prove that you DON'T know something, which is impossible.
You would be guilty until proven innocent, which cannot be proven.
Any law trying to stop or restrict Bitcoin usage is nothing less than a crime against humanity.
IMHO, the Bitcoin community should do everything in its power to prevent such laws. Your ability to use a communications network shouldn't depend on where you were born.
Do your part and educate as many people as you can as often as possible.
Speech is never free but always costly. It's high time to separate speech and state!
