I am not sure why this is so bad. No one can steal your money or car keys or even your CC card, if this chip is implanted into you for multiple purposes.
Who cares if they can track down every of your steps. After all, you are not doing anything illegal, so you shouldn t care. The government just wants your best so they should be allowed to know every of your steps.
If they ever use this to launch a laser guided cruise missile onto you, then it simply means you were a terrorist.
Please stop opposing the new world order and accept your governments as your best caring friends without questioning, because history has shown that governments can never turn tyrannical given the chance.
