you always need a registrar which has to be  life-time member already. Hence either you have a life-time member already that can register your account (ie. pay for the tranaction fee) or you will need to use a faucet (which does exactly that for you)

probably by creating a public key and sending funds to it just like with bts1.0.
but i might be wrong idk

EDIT:

Is it possible, and how?
