Seems that we can’t both get what we want.
A potential solution is that you get your anonymous phone line but my phone provider simply refuses to let you call me with it.
Of course then we need to extend the same principle to data and to IP traffic originating from your device. If you don’t want to be traceable it seems reasonable that services should have the right to refuse to handle IP traffic you generate.
Would such a half-baked level of network access suit your needs?
Why can't you? They don't want to provide info for a credit check, you want human accountability. All that requires is for them to use a debit card for whatever service (prepaid or postpaid). Law enforcement can trace that if needed. No need for credit checks or really any other information directly in the hands of the telco.
I don't think it's necessary to go this far. The provider could indicate something like "CANNOT VERIFY NUMBER". I imagine most people would block such calls.
I would like anonymous political posts to be untraceable by the government.
I can't even get all of what I want.
