If it is taken at face value, I can=E2=80=99t see anything that prevents an adversary from typing your name and signing away some of your possessions. With hand-written signatures, the assumption is that your signature is sufficiently complex that another person cannot duplicate it in a way that a graphologist wouldn=E2=80=99t detect. With GPG, the assumption is th= at you control your private key and that it cannot be brute-forced in a realistic time frame.
