No, the point is that "losing cellphone signal in an emergency" is being relied on as a justification for why you can't allow independent sales of apps on iOS,the fact is you already have no guarantee that you'll have cellphone service at any time, so it's an invalid justification.
It presumes that independent appstores for iOS would be worse for malware, for which there's no evidence (given the Mac allows independently sold apps to have the full Apple-signed cryptographic integrity the opposite is true), and presupposes that the Apple appstore doesn't already have malware, which it does.
