I guess the analogy is not perfect since when making a phone call you're using the network (which you're "renting"). In that sense the callers are blocked from using that network, which makes sense (this would be equiv from being banned from uploading malicious apk to an app store I guess)

What I am saying is that I have not been stopped from taking calls from unknown numbers just because the call might be a scam. Likewise I don't wanna be stopped from installing an apk just because it might be a scam.
