I don’t see that as a coherent worldview. If you can be force-injected on the say-so of government officials, you not only don’t have property rights, you don’t have rights to your own bloodstream.

To the extent government can’t be trusted with the currency, why on earth would you trust them with the contents of your bloodstream and that of your kids?

This is not to say if you *do* trust them in a particular instance you shouldn’t be free to jab yourself, but that’s very different than forcing your fellow citizen to take medicine he doesn’t want.
