Bitcoin is a conventional unit that you can buy and transfer to your balance, consisting of 64 digits known only to You. To storage and transportation do not need to have to carry in addition nothing to this password. Your accounts, apartments and cottages can be taken away by the court or the Communists can seize power, take everything, and in return give a room and drive you to work, but they will not be able to take bitcoin if they do not know that You have a password
In other words, nothing (people, government or just anybody) can be able to touch your Bitcoin because the owner of it is the only one who has the necessary details (like private keys or passwords) on its use, transfer or spending. However, we should not oversimplify the power of the government on this matter as they still can make things definitely difficult for Bitcoin holders -- for example if there is no approved crypto exchange within your country it can be discouraging to hold some.
