This is only if the end user allows seizure. If I have only a 12-word seed in my memory and not a single private key written down anywhere in my house and no bitcoin wallet installed on any computer, you have absolutely no way of confiscating anything. It's something that a lot of outsiders do not even realize. Bitcoin is actually entirely un-confiscatable. If someone commits private keys to memory or entirely encrypts and off-sites private keys, exactly how can the money be confiscated? It cannot be confiscated. Any human in the world can move freely about the globe at this point in time with billions of asset value solely residing inside their brain. Import that memory into any mobile or desktop client wallet anywhere in the world, or recite the key secretly to someone else they trust anywhere in the world.
